Radioss怎么设置多核求解

我在HyperMesh里划分网格,设置好边界条件和工况后,直接用Radioss求解,发现CPU只占到13%最大。

机器是双4核CPU,请问可以设置成多核求解吗,怎么设置?

option输入栏加
-ncpu 8

谢谢你,后来问了一个他们的工作人员,也是这么告诉我的,-cpu n

我看帮助里,也是这么写的,可是我加上这个之后CPU的占用率还是那么多...

Engine Keyword

/PROC - Number of Processors

Description

Number of processors.

Format

/PROC/N/M

Data
Description

N
Number of MIMD processors for this run.

M
Minimum number of MIMD processors for this run.

Default = N


Comments

1. This option has no effect in the MPP (SPMD) version: the number of processors is defined in RADIOSS Starter by domain decomposition.

2. /PROC is only applied for RADIOSS SMP parallel version (for RADIOSS SPMD parallel version, the number of processors is set in the Runname_0000.rad input deck using the /SPMD option).

3. For Flexlm type licenses:

• if the number of available licenses is greater or equal to N, the computation runs normally on N processors.

• if the number of available licenses is between N and M, the computation runs on the number of available processors.

• if the number of available licenses is lower than M, the computation does not run.

在求解时option栏输入 -CPU 4    注意CPU和4之间是有空格的

按照楼上几位的方法进行设置,还是无法使用多个cpu进行计算。

使用-ncpu(或者-nt,-nt是通用,bulk和block都可以用),altair的软件因为本身的限制,调用cpu不会超过50%
