  1. Hi, Below are the different approach to automate the process Approach 1 Import a CAD (Imported CAD should contains groups / colors) Generate mesh Transfer the groups from CAD to mesh Assign loads based on groups In this approach, when we bring the new model, the group / color information should be present in the CAD. In this way, we can fully automate the process Approach 2 Import a CAD (Imported CAD does not have groups / colors) Import group template (Contains empty groups with standardized group names) Generate mesh Transfer groups from CAD to mesh Assign loads based on groups In this approach, step 1 and 2 is manual. This is semi automated process. Refer the attached "Con_rod_automation.mp4" video. Approach 3 Import a CAD (Imported CAD does not have groups / colors) Using select features tool (body right click > Select features), identify the features and create group Generate mesh Transfer groups from CAD to mesh Assign loads based on groups This approach is fully automated. Refer "How to record python script?" tutorial in SimLab help page. Click on F1 will take you to the help page. Kindly try any of the above approach which suits your process. Let me know if you have any difficulty. Con_rod_automation.mp4
  2. Hi, In SimLab, we have convergence study tool. This will automatically do the mesh refinement on the high stress regions. Please refer the attached video for the reference.
  3. Hi, We have Tile option available under View menu. This will be useful to compare design 1 & design 2. Kindly refer the attached video. SplitView.mp4
  4. Hi, In this video, the script is recorded using Jscript. If you record the script in Jscript format, then you can use "Project > Play > Interactive" to execute the script step by step. If you record the script Python format, as you mentioned, we need to link Altair compose to execute the script step by step. We will create another video on how to record python script and how to execute the script. Sorry for the inconvenience caused. Note : Since, python version differs between SimLab and Compose, it is not working. Please configure Altair compose 2019.2 with SimLab 2019.2. It will work fine.
  5. Hi, I will check this and get back you. One suggestion is, after you model 1/4 of the body, use transform tool and mirror the body to get the whole model and then solve it to get results for whole model.
  6. Hi, Which join operation are you performing? Do you want preserve the adjacent faces of the joined face? Please give some details. For example, If you are joining 2 cylinders, and both the cylinders (contact faces) having same node count on the circumference, the use the align option and select the axi symmetry body. It will join and create iso mesh on the common face. Thanks & Regards, Santhoshkumar
  7. Hi, SimLab has its own convergence tool. Please refer the attached video and replicate the same in your model.
  8. Hi Harikrishnan, I checked with the development team. You are correct. There is a regression in SimLab 2019.1 version where the mid nodes are not followed the geometry during tetra mesh with volume layer mesh control. This issue is fixed in SimLab 2019.2 version. Can you please try this in SimLab 2019.2 version? Download SimLab 2019.2 version from https://connect.altair.com/ Sorry for the inconvenience caused.
  9. Hi Harikrishnan, I checked the 2nd order tetra mesh in SimLab 2019 version. Mid nodes are projecting on the geometry. I did the following 4 cases, Case 1 Import CAD geometry Generated volume mesh using Mesh > 3D Create > Volume mesh. I have used Tet10 as element type. In this case, mid nodes are projecting on the geometry Case 2 Import CAD geometry Generated surface mesh using Mesh > 2D Create > Surface mesh. I have used Tri6 as element type. Then, generated volume mesh using Mesh > 3D Create > Volume mesh. I have used Tet10 as element type. In this case, mid nodes are projecting on the geometry Case 3 Import CAD geometry Assigned body mesh control Mesh > 2D Create > Mesh controls. I have used Tet10 quadratic as element type. Generated surface mesh using Mesh > 2D Create > Surface mesh. Then, generated volume mesh using Mesh > 3D Create > Volume mesh. I have used Tet10 as element type. In this case, mid nodes are projecting on the geometry Case 4 Import CAD geometry Generated surface mesh using Mesh > 2D Create > Surface mesh. I have used Tri3 as element type. Then, generated volume mesh using Mesh > 3D Create > Volume mesh. I have used Tet10 as element type. In this case, mid nodes are not projected on the geometry Only in case 4, mid nodes are not following the geometry. Can you please let me know the steps you followed to generate 2nd order Tetra mesh? If you following the steps used in Case 1, 2 and 3, it will follow the mid nodes on the geometry. Hope this help you.
  10. Hi, Middle mouse button click will fix the rotation center. Please refer the attached image.
  11. Hi, Go to Mesh > 3D Create > Acoustic mesh. This will create mesh for acoustic analysis.
  12. Hi, In case NX, either you can use "Convert to Parasolid" option or you can export as Parasolid file in NX and import inside SimLab. In case of SW, you can directly import the SolidWorks model in SimLab. Please refer the below image.
  13. Hi, Currently, convergence curve plot is not supported in SimLab. We are working on this. Once it is completed, I will let you know.
  14. Hi, Go to Inspect > Mass Properties to find the CG of a component.
  15. Hi, These are different readers available in SimLab to import STEP models. STEP models are translated models. So, we need to choose the STEP reader according the STEP model. If the STEP model is written from CATIA software, then use SimLab reader to import. If the STEP model is written out from other system, then my suggestion is to go with either "Convert to Parasolid" or "External reader".
