How to add force/moment values from a file to a remote force and moment load using scripting?

Erik Kostson

Say we have a remote force and moment defined inside mechanical, and we want to automatically assign magnitude values to these by reading this data from an excel file. Further more we would like to automate this process inside mechanical using scripting.

One possible way of doing this is shown below:

import clr

clr.AddReference("Microsoft.Office.Interop.Excel")
import Microsoft.Office.Interop.Excel as Excel
excel = Excel.ApplicationClass()


## Create Windows explorer pop-up
filename = r'D:\myload.xlsx' # open this file
workbook = excel.Workbooks.Open(filename)
inputdata=workbook.Worksheets("ForceMoment").Select()# Select Worksheet by Name 
ws1 = workbook.Worksheets("ForceMoment")

Fx=((ws1.Cells(1,1).Value2)) # read first row and first column
Fy=((ws1.Cells(1,2).Value2)) # etc
Fz=((ws1.Cells(1,3).Value2))

Mx=((ws1.Cells(1,4).Value2))
My=((ws1.Cells(1,5).Value2))
Mz=((ws1.Cells(1,6).Value2))

excel.Application.Quit()
excel.Quit()

rf=ExtAPI.DataModel.GetObjectsByName('Remote Force')[0] # get force
rm=ExtAPI.DataModel.GetObjectsByName('Moment')[0] # get moment

unF=ExtAPI.DataModel.CurrentConsistentUnitFromQuantityName('Force')
unM=ExtAPI.DataModel.CurrentConsistentUnitFromQuantityName('Moment')

rf.XComponent.Output.SetDiscreteValue(0, Quantity(Fx, unF)) # assign loads
rf.YComponent.Output.SetDiscreteValue(0, Quantity(Fy, unF))
rf.ZComponent.Output.SetDiscreteValue(0, Quantity(Fz, unF))

rm.XComponent.Output.SetDiscreteValue(0, Quantity(Mx, unM))
rm.YComponent.Output.SetDiscreteValue(0, Quantity(My, unM))
rm.ZComponent.Output.SetDiscreteValue(0, Quantity(Mz, unM))
