In this version:
To use the op=mod parameter, one must insert op=mod before op=new in the Keyword editor:
Download: Downloads – PrePoMax
I considered adding support for the op parameter in the Step controls editor. In CalculiX, the step controls are meant to set the solver parameters during incrementation. So they have a special purpose. But in PrePoMax, I could add an additional control parameter called Op, which would have entries as Boundary, Cload, Dload, Temperature … and the possibility to switch from the default “new” value to a “mod” value.
The problem I see is that these op settings would not be visible in the FE Model tree. The user could easily forget about them.
What do you think?
I am still looking for an example where the op=new settings cannot perform the required task…
Would be nice to have an option to change this somewhere without having to edit the keywords manually. Maybe when editing a load/BC ?
Perhaps support for *CONTROLS should come with a warning like in Abaqus:
We’ve seen too many cases of misuse of this keyword.
I don’t think this would be the best place. Imagine having a concentrated load and a surface traction load in the same step. If the op parameter is changed to op=mod for the concentrated force, it is automatically changed for all other *Cload keywords, as is surface traction internally (at least that is how I understand it). So, I considered adding this setting to a step instead of to the load.
I went through topics on this forum, but I still feel that op=new is more powerful and can do everything the op=mod can do. While the op=mod cannot do everything the op=new can do - like disable a load. So if I add it, I would like to keep its setting hidden somewhere deep - not to the Step editor. That is why I was thinking about Controls editor.
I can add a warning like this copied from the Calculix manual to when opening the Controls editor.
I was thinking that the other loads/BCs of the same kind could automatically adapt to the new setting but it’s not a perfect solution either. The step controls editor might be a good place because this setting wouldn’t be changed so often. In the future, BC/load manager could be the best location.
