Good day all,
I have been exploring the capabilities of ccx/cgx and I have a very basic question on the use of ccx and cgx with respect to shell elements.
I have tried running a few of the test validation cases with v 21, and on my system the cgx output looks to have large displacement errors.
I am running on a windows box within a MINGW64 Bash shell using the Calculix running environment.
As an example, if I run ccx on shell1lin.inp from the Calculix2.21 test set
It is as if the internally generated 3D solid nodes for the shell are going off into space…
I have tried a few shell input models, and all have similar distorted views. I am obviously doing something very wrong.
Any help would be greatly appreciated.
Thanks,
Chris
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.
Those results look like the 3 digit exponent problem that happens with some builds on Windows. Floating point values in the .frd file should have 2 digit exponents so if you see 3 then it’ll be that. It’s extra suspicious that your CGX is showing 3 digit exponents in the screenshot.
One fix is set the environment variable PRINTF_EXPONENT_DIGITS = 2
Perfect. Thanks Victor.
I had noticed that difference between the two FRD files, and was having a peek at the frd code… The windows build published on dhondt.de works without issue… just my gcc build has an issue. I’ll set the switch and rebuild.
