    import hm

    import hm.entities as ent

    elems = hm.Collection(model,ent.Element)

    model.renumbersolverid(collection=elems,start_id=1,incr_val=1,offset_val=1,offset_flag=0,reserved_1=0,reserved_2=0,reserved_3=0)

    nodes = hm.Collection(model,ent.Node)

    model.renumbersolverid(collection=nodes,start_id=100,incr_val=1,offset_val=1,offset_flag=0,reserved_1=0,reserved_2=0,reserved_3=0)

    You are welcome Saravanan.

    For that purpose, you just need to change the collection instantiation to collect specific elems. 

    For how to, you can check out the links below and their contexts:
