如题,我在计算导线舞动的瞬态动力学分析时,出现了如下警告,初步分析是内存不足的原因,但是我用的是工作站,配置很高:CPU是24核,内存96G.我在product launcher里面设置total workspace 20480MB,dataspace 512MB,同时设置use shared-memory parallel(SMP) number of processors 设置为10(计划运用10个处理器)。但是计算过程中总是出现如下警告
*** WARNING *** CP = 108.733 TIME= 15:45:38
Pivoting has been activated for the Sparse Matrix Solver. The memory
required may greatly exceed predicted amount. In that event rerun
with increased memory using -m option (refer to the Basic Analysis
Procedures Guide, Ch. 19).
0***** process error reported by subroutine xdslfa
see xdslfa abstract (ier = -507)
*** WARNING *** CP = 165.096 TIME= 15:45:48
There is not enough memory for the Sparse Matrix solver to proceed in
the incore memory mode. The Sparse Matrix solver will now restart
using the optimal out-of-core memory mode.

相信很多大型运算都会有类似问题,恳请高人指点该如何设置ansys |
