Is it possible to split quad elements and keep the applied pressure (PLOAD cards).
Guys, Is it possible to split quad elements and keep the applied pressure (PLOAD)? See the screenshot. I split one QUAD element using 2D/split/plate elements/split all sides, but the pressure disappeared. I want to split and keep that -4.2 psi at all 4 new QUAD elements.
Thank you!

Hi,
Since version 2021, there is a new option called "Automatically update sets to mesh changes", allowing to update sets of nodes and/or elements in case of re-meshing. Thus, if a pressure (or any load/contact surface...) is defined on element set, then pressure will be automatically mapped on the new set in case of remeshing.
This is one advantage of the new load management => to define loads and boundary conditions as distributed loads on sets. More details here: https://help.altair.com/hwdesktop/hwx/topics/pre_processing/entities/loads_r.htm
This solution is highlighted in the attached video.
For a model with classic loads (as in your screenshot), you must process in two steps: first create a field to store the initial pressure loads and then realize the field to map the pressure value on the new mesh.

Thank you! It works with fields. I also created a tcl script that gets the value of the applied pressure (or several pressures) from the selected QUAD element, splits that element, and applies the pressure to 4 new QUAD elements.
p.s. Classic loads are because I imported the model from the Nastran file.
