Good day,
I am having issues with fully coupling two physics.
My system contains the solid mechanics physics coupled with a general form PDE to model concentration change and the diffusive properties of a spherical particle.
the solid mechanics stress results depend on the concentration results (solved for by the general form PDE) and the concentration results depend on the stress results.
Before solving anything I am defining my stresses ( that will be solved in the solid mechanics physics) as
sigx = solid.sx
sigy = solid.sy
sigz = solid.sz
so that I can write my PDE that involves these stresses.
My question is: Am I naming these variable wrong in regards to suitable convention? I ask because it does not allow me to run my problem as it is saying that the variables cannot be determined.
