Topic: For Node and element numbering?

In node and element records of your input format, should the number be sequentially continuous?

That is, is the following lines possible?

============================================

ndofman 3 nelem 3 ncrosssect  1 nmat 1 nbc 2 nic 0 nltf  1
node 1 coords 3 0.  0.  0.  bc 2 1 1
node 5 coords 3 5.  0.  0.  bc 2 0 1   lcs 6 0.8660254 0.0 0.5 0.0 1.0 0.0
node 7 coords 3 0.  0. 10.  bc 2 0 0  load 1 2
Truss2d 1 nodes 2 1 5 mat 1 crossSect 1
Truss2d 2 nodes 2 1 7 mat 1 crossSect 1
Truss2d 4 nodes 2 5 7 mat 1 crossSect 1

=============================================

In the test samples, our attempts were failed.

We do not always do continuous numbering of nodes and elements since they are often inserted and deleted in our problem domain.

Thanks

Re: For Node and element numbering?

Hi,

at present, a continuous numbering of nodes and elements is required. This is required in order to achieve fast component access using component number (stored in an array data structure, so continuous indexes are needed). However, the modification, based on internal renumbering and keeping original number as a label will not be difficult to implement. At present, only random component order is allowed, but numbering must be continuous.
