Can stress be transmitted to calculix instead of force in FSI?

Using preCICE

Hello,
I want to know how to transmit the stress calculated by openfoam to calculix instead of force in FSI?
Can stress be transmitted to calculix instead of force in FSI calculations?

Thanks

Hi, fan_wu

When I read the openfoam adapter code, I found out that there are four data can be used for coupling, force, stress, displacement, displacementDelta. So I think it’s possible to use stress instead of force, although I don’t know how the stress can be used hhh :grin:.

This is the configuration documentation page of the CalculiX adapter: Configure the CalculiX adapter | preCICE - The Coupling Library

Unfortunately, the CalculiX adapter does not support reading stresses at the moment, but it should not be too complicated to add it:

I have not tried it, but it was already suggested in the issue that reading Pressure could work if you only need the normal stress.
