But the simulation failed. At the Marc out file, exit 1 error message is below The number of elements associated with a distributed load exceeds the maximum number given on the SIZING, DIST LOADS or FLUXES parameters. This usually happens in the history definition, when a new distributed load is added, or the number of elements is increased. Increase the value on the parameter. Note that this cannot be done in a restarted analysis, it must be done beginning with increment zero. At the Admas msg file, error message is below. ---- START: ERROR ---- Simulation is failed. CoSim engine detects exception: Too many recycles occured during Cutback. Simulation time is 3.970686979E+00 ---- END: ERROR ---- No matter how I tried to fix this issue, I couldn't fix this.

I have displayed the results of both the structural and fluid analyses in scPOST, as I understand this is possible. However, since the deformation on the structural side is small, it is difficult for me to interpret the results. Is there a way to enlarge the deformation to better visualize what is happening? Thank you very much in advance!

However, in applications where the mesh element distortions are more challenging to handle, such as with significant component rotations or large displacements, I opt for the LDC (Linear Displacement Combination) or RBF (Radial Basis Function), adjusting the number of control points.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/msc-cosim/f/fsi/73813/what-type-of-mesh-deformation-do-you-use-in-scflow-in-case-of-fsiFri, 21 Mar 2025 04:34:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:6b789ced-4522-47aa-9676-ee500c401f05Laurent DelmasWhen dealing with FSI, what type of mesh deformation algorithm do you use versus the target application.
