Why do solutions with radiation superelements requires so much memory? The customer has a radiation model consisting of a database and several *.sub files of up to 100 MB each (total 784 MB). There are 67,000 nodes. The model seems to need 3.5 GB of memory which is much more than expected. Is this an expected amount of memory for a radiation model?

For historical reasons, 3 copies of the radiation matrices are stored in memory, which accounts for the unusually large memory requirement. The amount of memory required in ANSYS 12.0 is expected to be less. |
