Adding loads to model from excel table
Hi. I am modelling a flanged pipe section with one end fixed, using an RBE2 spider, and the other seeing reaction forces from multiple load cases. There are 9 load cases each with its own load step and each case has multiple forces and moments. All loads are acting on the same node, just in different load steps.
Every time I make changes to the flange, the RBE2 disconnects and the loads gets removed from the RBE2 centre node. I have to manually add the loads again so that the LOADADD card can recognize the combined load cases.
Is there a way to import loads from excel and associate them with a specific node listed in the excel file?

I have this script here that maked more or less what you need.
But, if you don't change the independent ID of your RBE2, it should not lose the loads.

# create loads based on a csv file for multiple loadcases
# csv should be written as: loadstep_name,node_id,dof,load_value
# csv example:
# subcaso1000,2,FX,123,0
# subcaso1000,2,FY,444,0
# subcaso2000,3,MX,222,1
