Two solid mechanics modules how can i avoid duplicated variabes

Hello everyone

in model library, a model named layered_plate simulated thermal deformation with two mechanics,considering
Liner Elastic and using the result from first mechanics as the intial stress can get a good result , but when considers elastoplastic with two mechanics,it failed with an error: deplicated variables,

i need to consider elastoplastic and use the initial stress same as Layer_plate,what i should do?

otherwise, if after computing some results ,how can i call it correctlly to another study process(the two studys compute seperated )

anything appreciate

thanks

Hi

but why 2 "solid" that duplicates everything yna you will have quite some work to separate each physics and to get them to coincide on the common boundaries ?

Isn't it easier with one "solid" and several domain nodes for the different types of physics, as I do not expect you have several domains with several different solid physics applying to the same domains, or ?

Good luck
