measure distance

Beta

Hi,

 

Is there any command or method to measure distance between nodes and comps.

I tried command: hm_measureshortestdistance but it said that, enity type comp is not supported.

Hi Toan,

Did you try with hm_getdistance 

The format is hm_getdistance entity_type id1 id2 syst_id

You cannot measure distance to a comp, because comp is a combination of nodes, elems, surfs, lines, points... you have to indicate which primary entity is, example

hm_measureshortestdistance nodes .... surfs ....

in that, surfs are pre-selected by *createmark surfs 1 'by comp' $the_comp_you_want_to_measure

hi,

 

@George P Johnson that command is used only for node-node or point-point. But thanks anyway\

@tinh well, my model contains only temp node and comp with element, there is no such thing like surface or line. That why I have to come here, looking for a solution.

ok simply replace surfs by 'nodes'

hm_measureshortestdistance nodes 1 .... nodes 2 ....

with node 2 is marked by *createmark nodes 1 'by comp id' $your_comp_id

I thought about that too,

 

But it's not the distance between node and comp, it is the distance between node and nearest comp node.

It will be wrong if the line between two nodes is not Perpendicular to comp.

Did you try with nodes->elems?

I tried, but no use,

The valid entities are nodes, lines, surfaces, solids and points.

May be there is no direct way to do that.

Hi

You can first search nodes-nodes

Then use hwat::utils::GetClosestElement

Then measure distance to that element
