Hello, following some recommendation on this forum, I am trying to use the EMOD command to create elements with an higher order only in one direction for a transient thermal simulation. As a test, I tried deleting all the mid nodes on elements (solid279) using the following commands:

MODMSH,DETACH

EMID,REMOVE,ALL

However, it is not doing anything. Am I missing something? Can the EMODIF command  be helpful in this case?

Thank you

The simple test below works for me.

/prep7
et,1,279
block,,1,,1,,1
esize,1
vmesh,1
modmsh,deta
emid,remove,all
elist   

elist output:

ELEM MAT TYP REL ESY SEC        NODES
 
       1   1   1   1   0   1      2     6     4     1     9    10    12    14
                                  0     0     0     0     0     0     0     0
                                  0     0     0     0

Hello, 

Thank you for the quick reply. I was using the graphical interface (Plot, Nodes) to verify the effetiveness of the command, but in the GUI the mid nodes still appear even though they have been deleted (I assume it is because the elements are still labeled as solid 279). However, using the command ELIST did show that indeed the mid nodes had been deleted.  

Cheers,

Leon

You could delete the unused mid-side nodes:

After emid command:

nsle,u        ! unselect nodes used by elements (corner nodes)

ndele,all    ! delete unused mid-side nodes
