RobotResultQueryParams always returns "I_RQRT_DONE"?

[Anonymous]

Hi All,

I am trying to improve the speed of extracting Robot results using the RobotResultQueryParams approach. I have read through all the posts but cant understand why RobotResultQueryParams always returns "I_RQRT_DONE". Here is my code:

           //Set the selection for all finite elements
            RobotSelection FESelection = robApp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_FINITE_ELEMENT);
            FESelection.FromText("All");

            //Set the selection for all load cases
            RobotSelection CasSelection = robApp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_CASE);
            CasSelection.FromText("All");

            //set the selection for all panels
            RobotSelection PanSelection = robApp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_PANEL);
            PanSelection.FromText("All");

            //set the selection for all nodes
            RobotSelection NodSelection = robApp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_NODE);
            NodSelection.FromText("All");

            //Fast Method
            IRobotResultQueryReturnType Res;
            RobotResultQueryParams RobResQueryParams;
            RobotResultRowSet RobResRowSet = new RobotResultRowSet();

            RobResQueryParams = robApp.CmpntFactory.Create(IRobotComponentType.I_CT_RESULT_QUERY_PARAMS);
            RobResQueryParams.SetParam(IRobotResultParamType.I_RPT_MULTI_THREADS, true);
            RobResQueryParams.SetParam(IRobotResultParamType.I_RPT_THREAD_COUNT, 4);
            RobResQueryParams.SetParam(IRobotResultParamType.I_RPT_SMOOTHING, IRobotFeResultSmoothing.I_FRS_SMOOTHING_WITHIN_A_PANEL);
            RobResQueryParams.SetParam(IRobotResultParamType.I_RPT_LAYER, IRobotFeLayerType.I_FLT_MIDDLE);

            //RobResQueryParams.Selection.Set(IRobotObjectType.I_OT_FINITE_ELEMENT, FESelection);
            //RobResQueryParams.Selection.Set(IRobotObjectType.I_OT_PANEL, PanSelection);
            RobResQueryParams.Selection.Set(IRobotObjectType.I_OT_FINITE_ELEMENT, NodSelection);
            RobResQueryParams.Selection.Set(IRobotObjectType.I_OT_CASE, CasSelection);

            RobResQueryParams.ResultIds.SetSize(8);
            RobResQueryParams.ResultIds.Set(1, 501);  //IRobotFeResultType.I_FRT_DETAILED_MXX
            RobResQueryParams.ResultIds.Set(2, 502);  //IRobotFeResultType.I_FRT_DETAILED_MYY
            RobResQueryParams.ResultIds.Set(3, 503);  //IRobotFeResultType.I_FRT_DETAILED_MXY
            RobResQueryParams.ResultIds.Set(4, 492);  //IRobotFeResultType.I_FRT_DETAILED_NXX
            RobResQueryParams.ResultIds.Set(5, 493);  //IRobotFeResultType.I_FRT_DETAILED_NYY
            RobResQueryParams.ResultIds.Set(6, 494);  //IRobotFeResultType.I_FRT_DETAILED_NXY
            RobResQueryParams.ResultIds.Set(7, 519);  //IRobotFeResultType.I_FRT_DETAILED_QXX
            RobResQueryParams.ResultIds.Set(8, 520);  //IRobotFeResultType.I_FRT_DETAILED_QYY

            Res = robApp.Project.Structure.Results.Query(RobResQueryParams, RobResRowSet);

Problem is with the last line "Res =...."

Has anyone got any idea why this is as I have tried multiple combinations of selecting cases with elements, nodes and finite elements.

Thank you!

That's a good sign. 😀

Now, you have all the results and you need to go thru then like this:

Dim ok As Boolean

ok = RobResRowSet.MoveFirst()
If ok = False Then Exit Do
While ok
' do something with  values and parameters

'RobResRowSet.CurrentRow.GetParam(I_RPT_PANEL)

'RobResRowSet.CurrentRow.GetParam(I_RPT_NODE))
'RobResRowSet.CurrentRow.GetParam(I_RPT_LOAD_CASE))
'RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(1)) * 0.001
'...
ok = RobResRowSet.MoveNext()
Wend

I was expecting that it should return "I_RQRT_MORE_AVAILABLE"?

This is because the rest of my code is like this:

while (Res == IRobotResultQueryReturnType.I_RQRT_MORE_AVAILABLE)
            {
                bool ok = RobResRowSet.MoveFirst();
                while (ok)
                {
                    numCas = RobResRowSet.CurrentRow.GetParam(IRobotResultParamType.I_RPT_LOAD_CASE);
                    numFe = RobResRowSet.CurrentRow.GetParam(IRobotResultParamType.I_RPT_ELEMENT);
                    res_nxx = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(1));
                    res_nyy = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(2));
                    res_nxy = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(3));
                    res_mxx = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(4));
                    res_myy = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(5));
                    res_mxy = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(6));
                    res_qxx = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(7));
                    res_qyy = RobResRowSet.CurrentRow.GetValue(RobResRowSet.ResultIds.Get(8));

                    //write to file here

                    ok = RobResRowSet.MoveNext();
                }
                Res = robApp.Project.Structure.Results.Query(RobResQueryParams, RobResRowSet);
            }

I have forced the code to jump into the while (ok) loop by manually overriding Res to equal "I_RQRT_MORE_AVAILABLE". But when I do this, the code breaks down on this line:

numFe = RobResRowSet.CurrentRow.GetParam(IRobotResultParamType.I_RPT_ELEMENT);

I get this error: "System.Runtime.InteropServices.COMException: 'Error HRESULT E_FAIL has been returned from a call to a COM component.'"

When I remove this line, the code executes perfectly! I want the line above to give me the finite element number.

On another note, the results come out in the following order: 1. load case 2. element. e.g.

Load     Element       Results......
  1         1          results here...
  2         1          results here... 
  3         1          results here... 
  1         2          results here... 
  2         2          results here... 
  3         2          results here... 
  etc...

I want the results to be produced like this:

Load     Element       Results......
  1         1          results here...
  1         2          results here... 
  2         1          results here... 
  2         2          results here... 
  3         1          results here... 
  3         2          results here... 
  etc...

Thanks a lot!!!

In your first post if you get, if you get I_RQRT_DONE, then you already have all results. If you get I_RQRT_MORE_AVAILABLE then you get only a part of your results and you should call your function again to get the other part, and so on... see API manual that gives you this info...

RobResRowSet.CurrentRow.GetParam(IRobotResultParamType.I_RPT_ELEMENT)

 I think it is not implemeted in API please see

Regarding order, I don't know how to control that (nor if there is a way). So after I get all the results (in a transient matrix for ex...) then I reorder as I want and finally put the results in the final place...

Sorry for not helping you more... regards

Thanks for the reply.

Surely there must be a way to get the finite element number for each of the results! Otherwise how do I know which finite element the results are for?

I’ll have to manipulate the results to get them into the right format then, which isn’t a problem.

"Surely there must be a way to get the finite element number for each of the results! Otherwise how do I know which finite element the results are for?" That's a good question for developers 😁. Maybe @Rafal.Gaweda can help you with this!

In this example, it is not a problem because you are asking results smoothed within panel, so you only need to know the node and the panel.
