bad result when calling `CriticalNodalSupportForce`

[dewloosh]

The COM server does not return the critical support forces correctly, when IAxisVMForces.CriticalNodalSupportForce or IAxisVMForces.CriticalNodalSupportForce2 is called.

A minimal code snippet to reproduce the problem. provided that an AxisVM is running and it was started with the /MULTIINSTANCECOMCLIENTS argument

from axisvm.com.client import start_AxisVM
from axisvm.com.axapp import IAxisVMApplication
from axisvm.com.axmodel import IAxisVMModel
from axisvm.examples.downloads import download_bernoulli_grid
import axisvm.com.tlb as axtlb

axapp: IAxisVMApplication = start_AxisVM(visible=True, join=True, daemon=False)
axapp.model = download_bernoulli_grid()

axmodel: IAxisVMModel = axapp.model
axforces = axmodel.Results.Forces

axforces.AnalysisType = axtlb.atLinearStatic
axforces.LoadLevelOrModeShapeOrTimeStep = 1
axforces.CombinationType = axtlb.ctAuto
axforces.Component=axtlb.nsfRz
axforces.MinMaxType=axtlb.mtMin

record = axforces.CriticalNodalSupportForce(NodalSupportId=5)[0]
Rz_min = record.Rz  # this value is wrong

According to the model, the value of Rz_min should be -72.018.

Another interesting phenomenon is that the API returns a smaller value for axtlb.mtMax than for axtlb.mtMin.

This is the node in the model:

I have tried to get the correct value with all possible combination types, other than axtlb.ctAuto, but none of them yields the correct value.

System details:

• Windows 11 (64 bit)
• Python 3.10.9
• AxisVM version: X7 R2b-qf3
