huge temporary files

Hello Altair Communuity,

I built a large finite element (FE) model and want to evaluate the stresses in the components. The problem is that HyperWorks creates a large number of temporary files during the calculation, which causes the calculation to break down when only a few elements are output (less than 100,000).
If the calculation runs successfully, the result files are not large either. (e.g., 8 GB).
The load case is a modal transient shock load (250 time steps, one shock direction) on a metal and carbon structure.
Does anyone know why this large number of temporary files is created? This does not occur with other models that have a similar number of elements and are made of metallic materials only.

Thanks in advance
