  1. Hi Ayil Have a check at the e-book, practical aspects of finite element analysis. https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/ Check this document too https://altairuniversity.com/learning-library/hypermesh-element-quality-check-and-mesh-styles/ Thanks

    Hi Dragon_heart You can create multiple load collectors for different load conditions as required with suitable card images. Then you can create different load cases also and assign the load collectors accordingly to your requirement. Thanks

    Error id 760.

    Hi vishruthdilip It seems like you have not assigned density value for a material. Check whether you have assigned necessary values for all the materials and try running it. If the error still exists please share the Radioss files. You can use the secure file transfer link if needed https://ftin.india.altair.com:8443/filedrop/~Ma3TaE Thanks

    Initial Penetrations In Interface

    Hi Sunilshanmugam Its advisable to create connectors using spring elements which is relatively easy. The current method is not recommended as it could affect the time step. Check this video on creating connectors using spring property https://www.youtube.com/watch?v=oQ5rancccVc Regarding the type 7 contact, it is recommended to create a contact surface for solid and select the same as master. For slaves select the slave nodes of the shell. You can create a contact surface from Analysis > contact surface Thanks

    Remaining time increasing.

    Hi vishruthdilip This is because the time step is dropping in your model. In this case while reviewing the OUT file, the time step drop is due to interface ID-3 in your model. Check and remove any penetration/intersection causing due to this interface ID-3. Still if the error exists try imposing a reasonable time step and run the analysis. Thanks
