Hi all; I'm trying to write a script that automatically generates a geometry and does the analysis in a for-next loop. It changes specified geometry properties in a for-next step like scaling the geometry. But I've got a problem about subdomain IDs. Although the main geometry isn't changed in the script (as i said it isonly scaled, there is no new generated subdomains) , the subdomain idsare changing. Because of this, i cannot specify the initial conditionscorrectly. I tried to use [g,st] = geomcsg(sl) command to getsubdomain IDs with their associated geometry IDs. So i could update thescript every time when i change the geometry properties. But i'vefailed because i couldn't reach the rows of variable st. Although typing variable st in Matlab command window gives therelation between geometries and subdomains, i couldnt reach it fromscript. It is seen as 2xm matrix in command window but nxm matrix ofdoubles in workspace so commands like st(1,:) doesnt work. Is there any suggestions to solve this problem or any idea why does it happen?: ) Thanks in advance..
