meshing of super element 21

Beitrag von wohenke »

sorry to bother you with this, I'm probably making a stupid error:
I'm trying to mesh a trivial type 21 super element as shown below
with type 21 finite elements. After importing the Z88ni.txt below and
starting to mesh Z88Aurora stops with the message: cannot read struture data!
Am I making a formatting error?
thanks and kind regards

Hello wohenke,

the problem is that no elements are generated. Therefore, the data can not be read. However, whether this is an input error or an error in the mesher I can not say at the moment. I'll be looking at the matter more closely, and then write again.

Hello Wohenke,

indeed, you are right! I checked your Z88NI.TXT file with the OpenSource Z88V14OS using the file checker Z88VRY.PL (see directory /perl) und ran it through the mapped mesher Z88N of Z88V14OS - works fine.

In fact, Z88Aurora stops with an error message - it seems to me that there is something wrong with Z88N from Z88Aurora - we will check this within the next days.

In the meantime, i have a work-around for you (a bit strange - i beg your pardon): Install the OpenSource Z88V14OS, feed the mesher Z88N of Z88V14OS with your Z88NI.TXT and import the generated Z88I1.TXT into Z88Aurora. I've tested it - works well. :wink:

We'll keep you informed. Thanks for your hint.

Best regards
Prof. Rieg
