fix command

[Jhno]

Hi,
is it possible to add a fix condition to a node after a first command was issued.
For example
In a previous step of the analysis I use the command
fix node 0 1 0
Then in another step I need to fix it in direction 1 and 3 also
fix node 1 1 1
will result in a warning because the node is already fixed in dof 2.
If I issue the command
fix node 1 0 1 will the first fix condition on dof 2 still be in place?

Is there a better way to do this? Thanks!

you can issue multiple fix, but you will also need to issue the remove sp command to remove fixities as the second fix just adds to the fixities
