LS DYNA Student version now is error?
<p>For some reason, I re-downloaded the student version, but it seems to have an import error.</p><p>I selected "Import STL file," but it showed as STEP. Selecting OBJ showed STL, and so on for other options.</p><p>However, when I switched back from STEP to STL, I still couldn't import the STL file.</p><p>How can I fix now? and is there another way to import the file?</p><p>I selected keyword -> include, but I still can't read the file.<br><br>Please help me!! <br>Thank in advance!</p>

Beam elements and blast
<p>Hello everyone.<br>Could you please tell me how to simulate an explosion near beam elements?<br>If I use DATABASE_BINARY_BLSTFOR, it doesn't record the explosion distortion data. The LOAD_BLAST_ENHANCED and LOAD_BLAST_SEGMENT maps are also useless for beam elements.<br>Which maps should I use?<br>Thanks.</p>

How to set beam elements in LOAD_BLAST_SEGMENT_SET
<p>Hello everyone.<br>When using the LOAD_BLAST_ENHANCED and LOAD_BLAST_SEGMENT_SET maps, you need to select a set segment in LOAD_BLAST_SEGMENT_SET. How do you set beam elements there? For example, if an explosion occurs near a network of beam wires.</p><p> </p>

Forming-Springback-Cutting Operation with SPH Part
<p>Hello,</p><p>I am performing an operation akin to forming-springback-cutting using an SPH part. In reality, it is an impact followed by a slow speed material test, so the SPH part undergoes large deformations.</p><p>I'm attempting a multi-stage simulation, but the second simulation always terminates with some form of a system or MPP error during initalization. I've tried adding a long damping period to the first test, and have also tried explicit dynamic relaxation and implicit springback using both restarts and dynain methods. However, whatever I do the "cutting" simulation never runs past initialization. </p>

LOAD_BLAST_ENHANCED isn’t working
<p>Hello everyone. I'm simulating a body impact with a mesh using beam elements in LS-Dyna Workbench.<br>Everything works. Now I decided to add an explosion when the body hits the mesh.<br>1. I selected the time when the body hits the mesh.<br>2. At this time, I activate the LOAD_BLAST_ENHANCED map. I set the explosion location using the element selector, I also set the explosion center and the explosion strength. But nothing happens.</p><p> </p><p></p><p>I also tested without the impacting body, simulating only the explosion on the mesh, and nothing happens:</p><p></p><p>Why? What's wrong?<br>Thank you.</p>
