(API) Speed up API (Extract results)

alfredmx — Tue, 16 May 2017 07:26:22 GMT

Hello,

I need to extract panel node results from multiple model files.

I'm using the following code to extract results:

'-----------------------------------------

Dim robotapp As IRobotApplication

robotapp = New RobotApplication

For i = 1 To grid1.Rows.Count - 2

robotapp.Project.Open(vecrutafile(i - 1))

robotapp.Project.Preferences.Units.Refresh()

Dim filename As String

filename = "\" & grid1(i, 1) & "_" & txtfile2pan.Text & ".csv"

Dim objWriter As New IO.StreamWriter(savepath & filename)

Dim RSelection As RobotSelection

RSelection = robotapp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_PANEL)

RSelection.FromText(elem)

Dim panelcoll As RobotObjObjectCollection

panelcoll = robotapp.Project.Structure.Objects.GetMany(RSelection)

Dim FileLines As String

FileLines = ""

FileLines = "Panel,Node,Case,UXX (cm),UYY (cm),WNorm. (cm),RXX (Deg),RYY (Deg)" & vbCrLf

For j = 1 To panelcoll.Count

Dim obj As IRobotObjObject

obj = panelcoll.Get(j)

Dim panelnum As Long

panelnum = obj.Number

Dim nodes As String

Dim nodesel As RobotSelection

Dim nodecoll As RobotNodeCollection

nodes = obj.Nodes

nodesel = robotapp.Project.Structure.Selections.Create(IRobotObjectType.I_OT_NODE)

nodesel.FromText(nodes)

nodecoll = robotapp.Project.Structure.Nodes.GetMany(nodesel)

Dim FEparams As New RobotFeResultParams

If combolayer.SelectedIndex = 0 Then

FEparams.Layer = IRobotFeLayerType.I_FLT_UPPER

ElseIf combolayer.SelectedIndex = 1 Then

FEparams.Layer = IRobotFeLayerType.I_FLT_MIDDLE

ElseIf combolayer.SelectedIndex = 2 Then

FEparams.Layer = IRobotFeLayerType.I_FLT_LOWER

Else

End If

FEparams.SetDirX(IRobotObjLocalXDirDefinitionType.I_OLXDDT_UNDEFINED, 0, 0, 0)

For k = 1 To nodecoll.Count

Dim node As IRobotNode

node = nodecoll.Get(k)

Dim nodenum As Long

nodenum = node.Number

FEparams.Node = node.Number

FEparams.Case = caso

Dim FEresults As RobotFeResultDetailed

FEresults = robotapp.Project.Structure.Results.FiniteElems.Detailed(FEparams)

FileLines = FileLines & " " & panelnum & ", " & nodenum & ", " & caso & ","

FileLines = FileLines & Format(FEresults.UXX * 100, "0.000") & ","

FileLines = FileLines & Format(FEresults.UYY * 100, "0.000") & ","

FileLines = FileLines & Format(FEresults.WNorm * 100, "0.000") & ","

FileLines = FileLines & Format(FEresults.RXX * (180 / Math.PI), "0.000") & ","

FileLines = FileLines & Format(FEresults.RYY * (180 / Math.PI), "0.000") & vbCrLf

objWriter.Write(FileLines)

objWriter.Close()

robotapp.Project.Close()

robotapp.Quit(IRobotQuitOption.I_QO_DISCARD_CHANGES)

'-----------------------------------------

The problem is that extracting results for each model is taking up to 8min (larger models with aprox 300 panels and 80 nodes per panel), and total number of models is around 80.

Is there any way to speed up the process?

Regards,

It seems to be working fine, because "FileLines" captures some results, but at some point within "While ok" loop a COM exception crashes the procees with HRESULT E_FAIL error. Any ideas?

It works fine.
Try to register Robot as admin.
If it does not help - send us Robot file to check it with this code.

Hello Rafal,

By register Robot as admin you mean post 8 in this topic, or just "Run as admin"?

Hello Rafal,

Sorry for the delay. I've been busy with an upcoming structural drawings delivery. In the meantime, I've been using current (slow) code to extract results from all model files. I will try suggested solution as soon as I have some free time. Thanks a lot for your help.

Hello, I'm currently trying to get the maximum principal stress inside FE panels and I bumped into the query solution (getting the results with the extreme result server gives inacurate results). I work with VBA from Excel and when I try to create the RobotResultRowSet object I get an error 429. I tried both with early and late binding : - Dim rowset as New RobotResultRowSet - Dim rowset as Object; Set rowset = CreateObject("Robot.ResultRowSet") but they both give the same error on the object's creation. I tried unregistering and registering robot.exe (with /unregserver) as admin, as suggested in other posts but that did nothing I also tried running Robot and/or excel as admin but it dosen't work neither. I even checked the class in the register and "Robot.ResultRowSet" exists in HKEY_CLASSES_ROOT with a supplied class id. Do you have a solution ? Thanks, Regards. PS : To the admin team : Since a few weeks, I can't seem to display the topic list in the forum board, or even create a new post in this board. I tried with both firefox and IE and the result is exactly the same. Is there a workaround ?

Could anyone point me in the direction of being able to achieve the above but for results for bars? I.E. forces and moments in a bar? I have had a look at changing the "IRobotFeResultType" but can't find an alternative.

I am working in C# and am trying to instantiate the class below like:

RobotResultRowSet RobResRowSet = new RobotResultRowSet();

... but I then get the following error?

System.Runtime.InteropServices.COMException: 'Retrieving the COM class factory for component with CLSID {F335E413-5241-418C-9421-A4D1B545F923} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).'

Any ideas?

Hi @thomas.channell

It must be 64 bit application \ exe as a result

Queryparams is only 64 bit.

Re: Speed up API (Extract results)

thomas.channell — Mon, 15 May 2017 15:14:02 GMT

Thanks for this :).

If we are running a 32 bit application/.exe, how much depreciation in speed would we expect.

Currently performing any interaction seems to lag a bit, hence the question.

Re: Speed up API (Extract results)

thomas.channell — Tue, 16 May 2017 06:55:44 GMT

Also, further to this, if there are any other methods of getting the results data out of Robot other than this method above and the method below?

RobotBarForceData forceData = robApp.Project.Structure.Results.Bars.Forces.Value(Convert.ToInt16(member.id), caseNumber, Point);

Re: Speed up API (Extract results)

Rafal.Gaweda — Tue, 16 May 2017 07:31:05 GMT

Hi @thomas.channell

how much depreciation in speed would we expect.

It depends on model size and amount of results. I can say, in general, "significant" difference.

RobotBarForceData forceData = robApp.Project.Structure.Results.Bars.Forces.Value(Convert.ToInt16(member.id), caseNumber, Point);

The above line in faster way, especially if you will use BarForceServer.Value(...) in the loop:

Dim BarForceServer As RobotBarForceServer
Set BarForceServer = RobApp.Project.Structure.Results.Bars.Forces
Dim BFD As RobotBarForceData

For i = 1 To BarCol.Count
    Set BFD = BarForceServer.Value(....)
    .....
Next i

You will find other servers in Robot API

Methods depend on your choice. You can use also:

RobApp.Project.Structure.Results.Extremes....
