Hi again,  
Well, after digging some more I located this thread by Calc\_em[https://calculix.discourse.group/t/help-on-installing-calculix-2-19-on-windows/1125/3](https://calculix.discourse.group/t/help-on-installing-calculix-2-19-on-windows/1125/3)

This version seems to work quite well. I tried one of the more complex models I am working with now, which contains S4, S3 Mass and T3D2 elements in it.

With a distributed pressure load, I get these results, which look quite good.

I see this v2.19 builds are quite different from the 2.21 builds… I will have to dig a bit more now, I do not like mystery fixes…
