I have two Abaqus analyses on two different meshes. One is an implicit dynamic diffusion problem and the other is an explicit dynamic mechanical problem. The mesh used in the diffusion problem is related to the mesh used in mechanical problem (but not the same). So the goal is in every certain time interval, temperature from diffusion problem should be transferred to the mechanical problem and the crack opening be passed to the diffusion problem.
How would you suggest to do an analysis like this?
Thanks.
Hello Roozbeh Rezakhani ,
if I understood you right, in the end you want to run Explicit simulation of Crack opening which will depend on mechanical boundary condition, as well as on the temperature of the part, which changes over time due to the heat diffusion. Am I right?
Sorry, maybe I am asking a silly quastion, but why can't you run both process (heat diffusion and mechanical deformation) in one Explicit simulation?
But to complete the exact task that you described could be very difficult. First of all, is it possible to create equal mesh for both simulation?
If yes, then you can try to use VUFIELD subroutine to define temperature of each node at exact point of time. More you can read here:

If you still want to use different mesh, then you firstly need to interpolate the temperature value from old to new mesh. It is nor straightforward, but could be perform using (for example) Python scripting.
Sincerely,
Pavlo
Hello,
I know A little about Abqus cuz my research is mainly on fluent. You have mentioned that you have two analyses but they are separate right?
in my bubble opinion, if these two mesh file have no connection nodes, it may impossible to generate the interaction, nor the coupling calculation can run.
I have used the workbench to analyze the fluid -solid interaction, the first thing I have to do is generate the mesh file contained both fluid model and solid model, then I can solve one model first and trans the results data into another model, then the interaction works.
I hope my experience is helpful and do wish you can solve your problem soon
best wishes
