API apply loads on nodes

AbelSV78 — Wed, 03 Dec 2014 13:34:31 GMT

Hi,

From VB.net, I have a Robot model with bars, nodes and loads cases that I have created.

I can't find the way to apply forces on nodes. Could you indicate me the variable for this and how to use it in VB.net?

Thank you in advance, regards

See the tutorial, You can learn a lot there:

'Generate new load case.

Dim cas As IRobotSimpleCase

Set cas = robapp.Project.Structure.Cases.CreateSimple(robapp.Project.Structure.Cases.FreeNumber, _

"Case_1", I_CN_EXPLOATATION, I_CAT_STATIC_LINEAR)

' Define load record types.

cas.Records.New I_LRT_NODE_FORCE

cas.Records.New I_LRT_BAR_UNIFORM

' Get the first created load record

Dim rec As IRobotLoadRecord

Set rec = cas.Records.Get(1)

'Define the list of objects to which load will be applied.

rec.Objects.FromText "1 2"

'Definie the operation direction and load value.

rec.SetValue I_NFRV_FX, 50000

'Define ALFA angle at which concentrated force acts in the structure node.

rec.SetValue I_NFRV_ALPHA, 0.52

'Get the second created load record.

Set rec = cas.Records.Get(2)

'Define the list of objects to which load will be applied.

rec.Objects.FromText "2do4"

'Define load direction and value.

rec.SetValue I_BURV_PZ, -110000

'Set auxilliary load parameters.

rec.SetValue I_BURV_LOCAL, True

rec.SetValue I_BURV_PROJECTION, True

Thank you so much, I got it:

cas = robapp.Project.Structure.Cases.Get(2)
cas.Records.[New](RobotOM.IRobotLoadRecordType.I_LRT_NODE_FORCE)
Dim rec As RobotOM.IRobotLoadRecord
rec = cas.Records.Get(1)
rec.Objects.FromText("1 2")
rec.SetValue(RobotOM.IRobotNodeForceRecordValues.I_NFRV_FZ, -55000)

Regards...
