ICEM surface trim and blocking projection
Hello my friends,
I've been doing a script in ICEM to produce a mesh based on a given geometry of guide vanes and stay vanes of a pump turbine and some parameters of the domain. It's a "almost 2D" domain, in order to simulate a 2D in CFX.
I've been facing some problems that I don't know how to overcome:
1) To create the surface, as it has a complicated geometry I've been using the "trim surface with curve". The script was done and working perfectly, and without changing anything, it stoped working this trim operation. I don't know why.. the lines and the plane are in the same plane (Z=0), and the lines form a closed perimeter.
2) When I create the 2D blocking, one of the sides of the blocking square that should appear "sometimes" is on the infinity. The most strange is that if I run the script a couple of times, the error may appear in a randomic way.
Does anyone has faced something like this, or might have a clue of what is happening?
Thanks in advance!
We can help you, if you can provide more information (pics, files e.g. tin, blk and script)
I'm uploading here the geometry .stp and the replay script. If you put both of them on the same folder (and change the paths on the replay script to this folder.. usually on the beggining and end of the script) you can run it, but it will only run well on a Linux machine!
The GV_domain has the problem on the blocking, while the GV_domain_bkp20.05 has a problem on the trim operation (which is my main problem).
Thanks a lot!!
Seems that the problem on the trim plane is that when I cut the circles to form the inlet and outlet lines of the domain (that are used to trim), there is a small gap that is formed (~0.01). Is there anywhere I can configure the allowed gap? Or somewhere I can merge points that are near?
