焊接热源选不中节点

最近在做焊接模拟，热源总是报错，请各位高手帮忙看下是哪儿的问题，小弟不胜感激。命令流如下，采用的是高斯热源，加载在面上的节点上

楼主是不是在做多热源啊？？

luliming 发表于 2010-4-18 22:51:17

不是多热源，热源要移动，要把先前一步加进的消除，设的那些是后便消除用的

luliming 发表于 2010-4-18 22:52:23

自己发现了模型的参数有点问题，考完试改过来之后还是选不中节点

wuyp802 发表于 2010-7-3 21:17:00

wuyp802 发表于 2010-7-3 21:18:41

你这是热源离散呀回答不对吧

lchl860625 发表于 2013-4-28 14:56:18

要把热源运动的距离和时间建立起关系

clozy 发表于 2014-2-28 13:42:09

楼主的问题解决了吗？
