Robot-API: create load 3 points surface

hvdsidf — Fri, 19 May 2017 06:59:53 GMT

Hi,

I'd like to create record type load 3 Points Surface with API (avec VBA):

I don't know how to set the 3 points (I_3PRV_N1, I_3PRV_N3, I_3PRV_N3). I have tried to give the node number but not work.

Please help me.

Otherwise, I have tried to do this manually, it doesn't work neither, see the message below:

Thanks in advance for your reply.

Hi Rafal,

I have tested your exemple, it create well the contour loads, but when the model is calculated, these loads are not taken in account (with message error).

In fact, it seems that the contour is not closed.

And when I closed the contour manually in Robot Interface (right click on the load and using the property of load), it works well.

So I think that we have to add a code to close the contour, but how to do?

Thanks for your help,

@hvdsidf

Example macro works with no problem (check case number, panel number, panel geometry, contour points coordinates)

Hi Rafal,

The macro create the contour load as we can see before Robot calculate.

But when Robot calculate, it dones'nt recognize this contour load (message error): I attache here the model in which there are the contour load created by API.

As I haved explained before, I have to close the contour load manually with Robot Interface (right click on the load and using the property of load), Robot recognize this contour load.

So I think that we have to add a code in API to close the contour, but how to do this?

Thanks for your help,

HI @hvdsidf

This works like here on your file:

Hi Rafal,

Have you tested the origin of my model? Is-there the message error?

If not, you can see the video of sreencast that I test yout API, you will see the error message (and there are NO REACTION in theses cases, it means that the loads are not taken in account)).

When I close manual the contour load, there is no longer error message and there are REACTION.

here is the video: http://autode.sk/2qGpR4u

But I'd like to close the contour load it with API.

Thanks in advance,

Hi @hvdsidf

Yes, I have seen message in your original file.

That's why I deleted these two records from Loads table before recording my video

Hi Rafal,

But do you know why there are the message error in my case (you can see them in my video) and the contour loads creating by API are not taken in account?

Thanks

Hi @hvdsidf

My mistake I posted different file version than I used.

One line in missing.

Add it to the code:

rec_1.SetVector 0, 0, 1

Hi @hvdsidf

Correct example attached.

hvdsidf — Mon, 22 May 2017 12:31:38 GMT

Hi Rafal,

It works well now.

Thank you very much.

So, it is neccessary to add the below (for load in direction Z)

recContour.SetVector 0, 0, 1

Thousand thanks,

For those who are trying to find how to do it in python, here is the example

load_case = 2 # case number 1 should exist or it will fail m = structure.Cases.Delete(load_case) #delete the case to avoid doubling when reload #create case case_rob_type = IRobotCaseNature.I_CN_WIND case = structure.Cases.CreateSimple(load_case,load_name, case_rob_type, IRobotCaseAnalizeType.I_CAT_STATIC_LINEAR) loads =[] #create load load_nmb = case.Records.New(IRobotLoadRecordType.I_LRT_IN_3_POINTS) load = structure.Cases.Get(load_case).Records.Get(load_nmb) load.SetPoint(1,4.67, -5.00, 0.00) # point A, X,Y,Z load.SetPoint(2,2.40, -5.00, 2.67) # point B, X,Y,Z load.SetPoint(3,4.67, -2.72, 2.67) # point C, X,Y,Z load.SetValue(IRobotIn3PointsRecordValues.I_3PRV_LOCAL_SYSTEM,1) #1 means True load.SetValue(IRobotIn3PointsRecordValues.I_3PRV_PZ1,1000) #in Pa load.SetValue(IRobotIn3PointsRecordValues.I_3PRV_PZ2,2000) load.SetValue(IRobotIn3PointsRecordValues.I_3PRV_PZ3,3000) loads.append(load) #apply load load.Objects.FromText(surfaces[0].Number)
