node in particular position on line

[skjoex]

Hi,

I am going to create a beam model of quite complex building. I would like to first create a solid model (keypoints+lines) which will be meshed with beam elements. But on some lines I need to have a node in special position ( I do not need an advice like "divide this line to have two lines" ).

I tried to use hard point, but then I realized that it can be used only to mesh areas and volumes.

Another way is to mesh a line with regular mesh and then modify the coordinates of the nearest node to have desired position. But node cannot be modified, because attached to line - so I need to write the nodes and elements to file, unmesh, delete all solid model, read node and element file and then change the position of node. But I want to keep a solid model as well...

Ok, speaking shortly: is there a way how to define a node in particular position on line ? thank you.

PS: attached file seem to be working, but if you type /ESHAPE,1 you will see that there is something wrong.

Maybe I am missing something, but using the LSBW and other mapped meshing techniques in combination with LMESH and ESIZE is the most effective and efficient way of doing this...?

Can you explain why this technique is not desirable, it might help us help you...

I am creating a beam model of building (let us say 500beams). In my model one line is one real beam. To this beam are connected perpendiculary another beams. So I want to have ability to select patricular line (in meaning particular real beam) and select everything attached to it (nodes, elements) and in the same time I need to create a nodes on the firs beam to be sure that all the beams will be connected...

Anyway I wrote that when you type /ESHAPE,1 there is something wrong - I have defined only one beam section, but after meshing and listing the attributes of elements I see that element no.4 has cross-section no.4, element no.5 section 5...So what I did ?
I just modiffed element cross section back to section 1. - Problem solved ! Now it is works.

Thank you anyway
