Assigning General Properties to a 1D Beam Element in CXX

AftabAftab
Hi I am having troubles assigning a 1D beam element, general properties that of I beam using a step file definition. The material type used is U1, somehow it is not recognised by the programme, using CXX card, a small 4 element model has been attached for illustration. Below error is reported. *ERROR reading *BEAM SECTION: *BEAM SECTION can only be used for beam elements. Element 1 is not a beam element.
*ERROR reading *BEAM SECTION: *BEAM SECTION can only be used for beam elements. Element 2 is not a beam element.
*ERROR reading *BEAM SECTION: *BEAM SECTION can only be used for beam elements. Element 3 is not a beam element.
*ERROR reading *BEAM SECTION: element set DEFAULT has not yet been defined.
*ERROR reading *BEAM SECTION. Card image: *BEAMSECTION,ELSET=DEFAULT,MATERIAL=MATERIAL,SECTION=GENERAL
*ERROR in calinput: at least one fatal error message while reading the input deck: CalculiX stops.

    A few problems:

    - Mecway doesn't make an ELSET called Default. I added one using a Named selection.
    - Mecway generates its own *BEAM SECTION keyword blocks which conflict with yours. I added modify keyword <omit *BEAM SECTION>.
    - U1 is not for non-linear analysis. I changed to Static 3D.
