i have what i supose to be an easy optimization problem to do it with ANSYS. it is a plate (1.75mx1.75m) with 4 holes wich i need to determine the optimum location (x,y) and radius (R)  to minimize the maximum Von Mises straining (SQV). Constraint: 0.04m<Ri<0.2m; Af>0.08*1.75*1.75. Af is the total area of holes and Ri his respective radius. P1=P2=1200N/m. Material: Steel: E=200GPa,v=0.29

Dear All,

I am modelling the cracking in concrete in Abaqus CAE using the Brittle cracking option in Abaqus.

Now i want to see the output results (Contours of cracks) like CRACK, CKE, CKSTAT etc.

But i dont know how to see that output

Can some one help me

Thanks

Kind Regards

I have sucessfully called and runed an ANSYS file from Matlab with this command.

! "C:\Program Files\Ansys Inc\v100\ANSYS\bin\intel\ansys100.exe" -b -i D:\ansys_file.txt -o  D:\outputfile.txt

Has any one try to run Abaqus from Matlab, and can you share the command for me ?

Hi All

How to find the modal frequencies of a wind turbine blade,

-Ravi Talawar

hello,

•      i simulate some process using shell elment, i find the results have big difference between abaqus and lsdyna. the abaqus results always show the stress in the thickness direction is zero. but the lsdyna is not. i don't know why? if some one know that, please give me some suggestions. i heard that the abaqus can not show that stress component. if not, how can i do to calculate that and fill it into the results file (.fil file). thank you!
