WS for electromagnetic field analysis (memory 1.5TB specification)

We received an inquiry from a customer about a workstation for electromagnetic field analysis.
The license of the software to be used is a contract of up to 12 cores, but there is a request to adopt a CPU of about 24 cores in consideration of future expandability.In addition, we request that the memory capacity be about 1.5TB.

Considering the desired memory capacity, guidance with a 2-CPU configuration is a prerequisite.
A 12-core CPU x 2 configuration is desirable, but since there is no perfect 12-core product in the current Xeon lineup, we have proposed a total of 1 core configurations with 16 2-core products, which is one level higher than your request.
