I'm working on this concrete beam with rebar going through it. These are all solid bodies the problem I believe is where the rebar touches the concrete. I believe Marc sees those elements as not 3d. Thanks for any help or suggestions.
If the rebars are 3D elements, then you need to use "Inserts" under Mentat - Toolbox to insert the rebar elements. You need to do this for the rebar to be properly connected to the host body.
The error message in the picture is for something else - the tetra4 elements do not have valid element type. To fix this problem, you need to go to "Jobs - Element Type - Solid - 134 and select all the tetra4 elements.
