February 11, 2021 at 2:16 pmKCPUTREVUSubscriberHi all,nWhile solving a problem in Ansys i have encountered this error message. 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 = 176 MB. nn Local memory allocated for solver = 298.707 MBn Local memory required for in-core solution = 252.979 MBn Local memory required for out-of-core solution = 165.334 MBnn Total memory allocated for solver = 597.229 MBn Total memory required for in-core solution = 505.867 MBn Total memory required for out-of-core solution = 330.976 MBn Total no of nodes are 62957. I am using 8 GB ram with 2 GB graphics. nPlease help me get out of this problem. Thank you,nnRegards,nKrishna Chaitanya n n n nn

February 19, 2021 at 9:38 pmGary StofanAnsys EmployeeThis can also happen if the model is not well constrained, i,e not enough supports. Try adding additional supports to verify.n
