While solving the Modal analysis i am gettin gthe following error , which i i feel because of memory issue only. Here i was using the quadratic elements , when i changed it into the linear elemnt it solved my modal analysis in just 20 minutes but quadratic it showing this error. As quadratic are better i wanted to use that element, so could please tell any possible solution . FYI my PC confiuration is 512 Gb Ram 3 Tb harddisk with 64 core.
Time at end of element matrix formulation CP = 222.84375.

The Distributed Sparse Matrix Solver used by the Block Lanczos
eigensolver is currently running in the in-core memory mode. This
memory mode uses the most amount of memory in order to avoid using the
hard drive as much as possible, which most often results in the
fastest solution time. This mode is recommended if enough physical
memory is present to accommodate all of the solver data.
Total memory available for LANCZOS = 115.954578 GB
