Sparse Matrix The solver has failed. Please check the error file fodr
possible causes.

Bisection may be activated if it is a nonlinear analysis.
*** ERROR *** CP = 170.328 TIME= 09:01:30
There is not enough memory for the Sparse Matrix solver to proceed.
Please increase the virtual memory on your system and/or increase the
work space memory and rerun ANSYS. The memory currently allocated by
ANSYS = 764 MB. The memory allocation attempted = 376 MB. The
largest block of ANSYS memory available for the Sparse Matrix solver =
311 MB.
*** WARNING *** CP = 33.609 TIME= 08:56:12
Mid-nodes of some elements have been modified to lie on straight edges
because of distortion with the original mid-nodes. This condition is
sometimes eliminated by tetrahedron element improvement when enabled.
Issue ESEL,,STRAIGHTENED to select such elements for listing or
plotting.
*** WARNING *** CP = 38.734 TIME= 08:56:24
Shape testing revealed that 1 of the 308131 new or modified elements
violate shape warning limits. To review test results, please see the
output file or issue the CHECK command.
*** WARNING *** CP = 54.984 TIME= 08:57:44
Previous testing revealed that 1 of the 308131 selected elements
violate shape warning limits. To review warning messages, please see
the output or error file, or issue the CHECK command.
*** ERROR *** --×îºËÐĵĴíÎó@@
A small negative equation solver pivot term has been encountered at the
UZ degree of freedom of node 2194. Check for an insufficiently
constrained model.
