I am working on not a very complex assembly (just 8 parts, but 3 of them are complex, obtained from scanning) of a stackable guide for dentistry. I am doing a FEM analysis (this is quite complex) for a scientific paper. When I open the saved analysis I get this message:

Allocation failed (8192 bytes).
An allocation of 8192 bytes failed.
Close the open documents that are useless, save your work, restart a new session.

All works fine (assembly, constraints, analysis, results etc), but it is slow (lot of time needed to compute the results). My computer is:

13th Gen Intel(R) Core(TM) i7-13620H (2.40 GHz), 32.0 GB RAM, NVIDIA GeForce RTX 4060 Laptop GPU (8 GB), Intel(R) UHD Graphics (128 MB), Windows 11 64-bit operating system, x64-based processor.

So I guess the physical 32 GB RAM it's not (should not be) really a problem, nor the processor or the graphics card. Please, how can I solve this issue in order to increase the speed (shorten the time) of the FEM analysis and get rid of this Incident report ?
