Welcome to the LS-DYNA Product Space

<p>Hello,</p><p>LS-Prepost (all recent versions up to 4.13, normal and DP, windows) has issues when opening files in read only directories on windows shares.</p><p>More specifically:</p>model files: when the input include INCLUDE_PATH_RELATIVE commands, the files are not found (and the model cannot be opened)opening binout files leads to crashes in recent versions. It works in old versions (4.7).<p>I tried various settings (do not write msg and cfile, use relative path) in the settings but without success.</p><p>Any solution? It would be great if it could be fixed. We use these a lot to access student results.</p><p>Thanks</p><p>Philippe</p>

<p><p>Greetings,</p><p>I have installed the Ansys license to run LS-DYNA. </p><div class="x_elementToProof" data-olk-copy-source="MessageBody">I was able to install  Ansys and run a simulation through LS RUN default solvers. However, when I try to run other versions of the LS-DYNA solver (executables) that I obtained from ftp.lstc.com, I get a licensing error. See below two screen shots. The first one shows that I changed the solver to ls-dyna_smp_d_R15... that I downloaded from LSTC website. Then the second screen shot shows that the software gives license error. Does anyone know why would this happen?<br><br><br><br></div><div class="x_elementToProof"> </div></p>

<p>I am using MAT_079 HYSTERETIC_SOIL with a prescribed damping curve via LCD. The manual / messag file states: "LCD can only reduce the damping compared with Masing, and a monotonically increasing difference between Masing damping and non-Masing damping is expected. Actual damping will not follow LCD if these rules are not observed."</p><p>My question is, if these conditions are not met for some strain entries along the curve, does LS Dyna ignore the entire curve throughout the whole analysis, or does it only default to Masing damping once the rules are not satisfied ? Below is a screenshot from the messag file of my analysis. Does this mean in this case my prescribed LCD curve was used except for the first three and last two entries ? Or was default Masing damping used during the entire analysis ?</p><p></p>

<p>I am using DUALCESE solver. Can someone help resolve the following error?</p><p> *** Error 200213 (DCESE+213)<br>On DUALCESE mesh      1 no element contains a face defined by nodes:<br>          1563527     1568678     1568679     1563528<br> </p><p>Regards,</p><p>Atish</p>

<p>Hi all,</p><p>I am trying to run a projectile impact case that observed spall failure using the Structured MMALE solver. I am using the Johnson-Cook strength model which allows a prescription of a pressure cutoff which I am assuming is where the spall strength can be input. However, I am not getting any spall behavior. Can spall be captured via structured ALE solver?</p><p>Thanks,</p><p>Peter</p>

<p>Hi all,</p><p>Does anyone know how to output the wave speed? I know it's material dependent, but I'd like to think that I could get an approximate bulk wave speed of c = sqrt(dP/dRho) at least? </p><p>Thanks,</p><p>Peter</p>

<p>Hi,</p><p>i made a simulation in LS-Dyna and i want to save the result from it to a Dynain-file. Is there a way to use this dynain file in Ansys Workbench or Mechanical AND add some other geometry (step-files). I know i can import keyword-files in workbench but i need to import some step-files additionally.</p>

<p>Hi,<br>I Am AbhiRam i have a problem in opening the TOYOTA yars ROOF TOP CRASH ANALYSIS file from ANSYS<br>website it when i download and try to open it in fusion 360 it does not support .K file so the file which i downladed is in .k file how can i convert that .k file format to .STEP format and if i tried to open that in<br>ls pre post it is showing some errors and how to solve it you can see the errors in the screenshort which i uploaded so can you please help me with it because its my btech project on ansys which i need to work on but it wont open at all</p>
