焊接应力场数据无法输出

本帖最后由 schuhi 于 2012-5-9 17:52 编辑

焊接热力耦合，计算完第一道焊缝的应力场时，可以输出变形场数据，但是无法输出应力场数据，提示The requested S data is not available ，the PLNSOL command is ignored
我的热分析单元是solid70，结构分析时转化成solid185.以前在计算的时候遇到只有应力场结果，却没有变形场，后来发现是约束不对，可是这次都加对了啊。不知道什么原因。求指导。

我用同样的文件在另一台电脑上计算了，却能输出应力场和变形场，两台电脑设置都一样啊。这个真的很不理解。

Make sure you request the element results before solving.
As we know, FE method get the deformation results first and then the stress, strain .. results. Normally, you don't need special operation to get the 2nd one. However, sometimes, such as in mode analysis, the programme just get the deformation because the switch for strain, stresses is turned off somehow.
So, you should make sure you request all results before solving.

PS: Sorry for the language, sth wrong with my keyboard.

IF I do as what you suggest ,another problem comes out. There are too many substept,which makes the fileimmense.
/config,nres,2000
Although the order above can exceed the capacity of substep ,the post1 become inconvenient.
If you have some great idea ,it will be a good news.

子步数可以人为控制啊，真需要那么多子步么？

可以不需要。这个我改过了。但是restart的次数可不可让它超过100次？

假如我这样设置的话，计算文件的大小一下子猛增到50G，但要是按照原先的设置

就输不出应力结果。这个真的有点头疼啊。我算的是焊接应力，焊接道数比较多，要是按照这样的话，迟早计算机硬盘不够用了。
