Calculate only some of the Load Combinations [SOLVED]

Help
1

Hello!
Is it possible to define specific combinations for calculation through Grasshopper and not all of the combinations at once?
In FEM-Design we would use the crosses to mark the chosen combinations for calculation:

Hi @Viktors! :slight_smile:

Yes, it is possible. You can use the Comb.Settings component to set the analysis types for different load combinations, just as you would do manually using the FEM-Design user interface.

I have attached a sample Grasshopper file below as an example of the workflow.

Hello there!
Thank you for the sample! I guess, I was maybe not specific enough. :smiley:
What I want to do is to prepare the setup for different load combinations like in the sample you provided, however, I wish to run only one specific load combination, say, the 2nd one in your sample. Can that be done?
I am trying to make a script for checking precast slab members. I would select plates in Tekla Structures and they appear in FEM-Design and are calculated for lifting (supports are placed at the lifting anchor locations, basic reinforcement mesh is inserted), but this same design can be used for ULS ands SLS check for exploitation during the design life, although at this stage I would like to prepare everything I can for ULS/SLS, but calculate slabs only for lifting.
Maybe you can develop similar input for the Comb.Settings component for calculation of specific combination similar to how you define which analysis to perform (NLE/PL/NLS/Cr etc.) using a list of boolean operators.

Hi @Viktors

Not yet unfortunately but it is a great idea. I will ask to give us access to it :slight_smile:

Unfortunately, the .fdscript file does not have that information and it might take some time before being able to give it to you.

Hi @Viktors! :wave:

I would like to inform you, that we have successfully implemented the ‘Calc’ option in the API. :rocket:
From the next release (version 23.3.0) you will be able to specify for which load combinations you want to perform the analysis. I hope you will enjoy it. :slightly_smiling_face:

P.S.: I’ve attached a sample Grasshopper file that you can open after the next release.
