Hello,
I'm doing an foot pressure analysis in Ansys with a insole and a suport (see picture pls).
The border conditions are very simple :
Top of tibia fibula and soft tissues = X=Y=Z=XR=YR=ZR=0
SUPORT= X=Y=XR=YR=ZR=0 Z=0,0004.
I have the following error:
*** ERROR *** CP = 156.875 TIME= 17:36:34
There is not enough memory for the Distributed Sparse Matrix Solver to
proceed. This is likely due to the use of pivoting while factoring
the matrix. Please increase the virtual memory on your system and/or
increase the work space memory and rerun the solver. Alternatively,
using the DSPOPTION command to switch to a different memory mode
and/or to specify additional memory for the solver may also help. The
memory currently allocated for the Distributed Sparse Matrix Solver
solver = 203 MB.
THANK YOU SO MUCH!!!

The Distributed Sparse Matrix Solver 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.

The Distributed Sparse Matrix Solver is currently running in the
out-of-core memory mode. This memory mode may provide significantly
worse performance compared to the in-core memory mode, depending on
the amount of available system memory and I/O speed. Please monitor
the solver performance to ensure that the large amount of I/O to the
solver files does not create a bottleneck for performance.
