For cases where the keyword editor has to be used, it would be awesome of for example multiple cases of keywords could be changed by a variable, set from the steps. Meaning for example, a step (as load case) with a hyperelastic element - might want to try several “durometers” with mooney-rivlin constants. Right now, one has to manually edit the constants for an analysis and run each one. If could automate, could step through several changes to the keyword definition. Not sure if possible at all in CalculiX to set a value to a variable name, and specify that elsewhere, but if possible, would had a nice QOL feature. ---

You can use this for some automation of PrePoMax: [A new developer/preview PrePoMax version v2.1.7 has been released - #2 by Matej](https://prepomax.discourse.group/t/a-new-developer-preview-prepomax-version-v2-1-7-has-been-released/1974/2) However, when it comes to keywords, CalculiX doesn’t have parameter studies (unlike Abaqus), but you could request this here: [GitHub · Where software is built](https://github.com/Dhondtguido/CalculiX/issues)
