Good evening,nI am running a Fluent simulation at steady-state and then beginning a transient part of the simulation. I am importing the resulting load profiles into Transient Structural. However, a challenge is that the simulation of transient structural is initialized from the zero-deformation condition, which is not correct.nI could run static structural and steady-state thermal analyses to get initial displacements at every position in the part. It appears that then I would need to attach those to the Mechanical simulation using APDL commands.nInstead, the ANSYS guide recommends providing initial displacements on the surfaces; however, I do not have uniform displacements on the surface and then the interior would still not have initial displacements though it should.nIs one of those methods best, or another method, for setting the initial deformations to be nonzero, and why?nThank you!n

Hello,nCould you please share a screenshot of how you are connecting the two analysis? nTransient analysis should take the loads from the static analysis as its initial conditions.nThanks.nKarthikn

Good evening, Karthik.nnThank you for your reply. Here is our setup. We are obtaining the load from a transient Fluent analysis:nnPlease let us know what you think.
