Truss Element with no length

[suusie]

Dear Sir/Madam;

I just want to know if the Truss element works fine if this truss element has no length.

When we use truss element which connects two nodes with identical positions, the following warning message appears:

WARNING Truss::setDomain() - truss 1 has zero length

Does this matter ?

Sue.
