HI, I have some problem when modeling contact with TARGE69 and CONTA175. Target elements are penetrating too much the contact elements when using keyopt(2)=1 (penalty algorithm). Any suggestion to solve the problem? Thanks. Lyes

Hi Brain, I'm familiar with the WHILE loop in Fortran, but my problem is that I don't know how tu use the 'par' argument. In Fortran, we could write: WHILE,A,LT,B,THEN .... ENDWHILE But with *DOWHILE in Ansys there is just the 'par' argument! why the loop exit when arg is equal to zero only? I...

Hi everybody, I would like to know how the *DOWHILE command works, and what is the argument "par"? Thank you. Lyes

It's an ANSYS command, it is used to simulate loops, but I don't know how does it work! Lyes

Hi everybody, I would like to know how the *DOWHILE command works, and what is the argument "par"? Thank you. Lyes

Good morning, I'am trying to use the tb,Chaboche to model 304L behaviour under cyclic load, but there is no information about this model, could someone give me help? Lyes.

Hi Brian, Thank you for you reply, In fact, I'm using CEINTF and NLGEOM commands in my model, I'm generatinh also contact area. during calculation ANSYS/LS-DYNA deletes the constraint equations imposed by CEINTF. I think that there is a conflict between constraints imposed by CEINTF command and...

Hello, I would like to get information about generating contact with ansys/ls-dyna. Is there any conflict when using NLGEOM and CEINTF? thanks. Lyes

Hi, thank you for your help, the problem that I had was the format of my file! I didn't give the right number of column. But now, every thing is OK!!! thanks for your help. Lyes

Hi, I'm using *tread command but it don't work, I don't no why. An error message appears *TREAD cannot open file Data.txt. For my Data.txt file, it is an Excel file that I saved as Unicode file. Is it the problem? Lyes.

Thank you Brian for your help, I'll try your advice, otherwise, I'll use the GUI, it's less flexible, but it should give me results. Thank you. Lyes.

I used the OUTRES command (OUTRES,,1) to get results for every substep in the RST file, but I didn't view any displacements, nor results are available!!! could it be a probelem of ANSYS LS-DYNA version or licence? I'm using : Simulation Environment: ANSYS Licence: ANSYS Structural/LS-DYNA ANSYS...

Thank you Brian for the information, I'm used to write a scipt in Notes pad, which I excute in ansys, and I do the same this time with ansys ls-dyna, in my script I always follow the same steps, /PREP7,/SOLU(finished with SOLVE command), than /POST1 to view my results (strains according to x, y...

Hi, I'm a new user of ANSYS LS_DYNA, I'm trying to model a hammer impact in the surface of steel sample. I do not use the GUI of ANSYS, I prefer to write a scipt that I load it in ANSYS for execution. No error message comes out in the end of the simulation, but the results are not available...
