  1. In File > Preferences, we have many useful options. In case of automation, preferences settings are not recorded in the script. If we need to utilize the preferences option during automation, do the following All settings in the Preferences dialog will be stored in ‘SimLabSetting.ini’ file which is available in the following location - C:\Users\<user name>\.altair\SimLab_V2019.2\simlab. Once the settings are defined in preferences dialog, take a copy of ‘SimLabSetting.ini’ file and save it locally. Set the environment variable SET SL_USER_DEFINED_SYSTEM_SETTING_FILE=\... setting file location...\ SimLabSetting.ini in the batch file from which SimLab is called. Once the above settings are done, execute the batch file, it will consider the preferences settings from the file defined in environment variable for automation.
  2. Hi, Here is an example for trim options. Hope it helps
  3. Hi, Can you turn off "Near by surfaces not overlapping" and "Penetrating surfaces" check box and then try convert to overlap? It will work. Refer the attached video for your reference. Also, attached a sample model used in the video. Convert_Overlap_Penetration.mp4 Intersection.gda
  4. Hi, Currently, SimLab does not support octree based mesh. We have a tool to generate voxel mesh. Please refer the attached image.
  5. Hi, Particle spacing is the distance between adjacent particles in the global coordinate. The particles are uniformly distributed along the global XYZ axis. This spacing is used when generating the particles for stationary parts, moving parts and the fluid regions. The above information I took from SimLab help page. After opening the "1 Click SPH creation" tool, press F1 will take you to the help page about this tool. If you are using SimLab 2019.3 or later version, we have introduced unit system in SimLab. Refer the attached image. If you are using older versions of SimLab, Specify the value for particle spacing based on model units. For example, if the model imported in Meter, then specify the particle spacing value in Meters. You have to make sure that the units are consistent.
  6. Hi, What is the CAD you are using? If you are using native CAD models, then mostly you will not get free edges and intersection after mesh. To resolve the free edges quickly, use Mesh > Modify > Fill Hole tool. By selecting the body, it will automatically find the free edges and fill. This is the easiest way. If the free edges are small cracks, then use Mesh > Modify > Fill cracks tool. Regarding resolving intersections, use, Mesh > Modify > By elements. or the way you suggested in the another method.
  7. Hi, CTRL + C option will keep the data in clipboard and we can paste the image in PPT. Note: No need to change the background color to white. CTRL + C will save the data in clipboard in white background.
  8. Hi, By applying fillet mesh control, we can avoid this kind of smaller elements. Did you applied any mesh controls on the faces which contains smaller elements? As you mentioned in the mail, you tried cleaning up by using some methods and SimLab crashed. Do you remember which operation crashed SimLab? If so, we will try to reproduce the crash and fix the issue. If possible, send me the model. We will assign mesh controls and send the output mesh.
  9. 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
  10. 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.
  11. 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
  12. 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.
  13. 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.
  14. 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
  15. Hi, SimLab has its own convergence tool. Please refer the attached video and replicate the same in your model.
