Hello Martin,
I've made a short test with the 3dSolid example and exported the result to txt. Unfortunaly the output seems not to give loads (x,y,z-forces) for all fea-nodes. Afer an reorder in libre office I saw some gaps?! That makes parsing more difficult. Is it a uniquely job?

Have a nice day
Karsten

Hi Karsten,
nope the routine has to be performed for different geometries/models after the proof of concept was successful.
I will check (FEA node export) this during the next days.
I performed a similar operation last year while using an export from ANSYS result txt-file (x-y-z & forces) and used this input in Cinema 4D for meatball modelling.
It worked very well for each node.

Best regards,
Martin

Hello Martin,

sounds interesting:-)
I've written a node to import text/csv-files. And a first test looks good! Read back the xyz coords works good (pointarray), if you have the sequence separated in a csv-file. The node supports also numarrays but it can't parse for fea-node numbers and fill missing infos.








Have a nice day
Karsten

p.s.: It sounds like a structural optimization algorythm for light weight structures!?!

Absolutely! That is the plan.
It goes in similar direction like Altair OptiStruct, however with improved surface quality and total control concerning the primatives (spheres, cylinders etc.) that are used as base bodies.
I suppose that Moi3d can do that with a good performance. :)

Best regards,
Martin

Hello Martin,

I'm also using fea for the job. I think it is a good choice to use the nodeeditor as a tool for that. Support of different geometries and different fea output formats are easy to handle, if some missing nodes are made. The mesh and output of calculix (.dat), openFOAM via ParaVIEW would be possible to support also. I don't have a look to ANSYS in the past, because I use the WB, but now I'm curious:-) I think it's also possible to select only the biggest joined object with a filter node. If you think a special script would do the job in a better way - the nodeditor can help to design the workflow and logic - the code can give you the examples.

Have a nice day
Karsten

p.s.: I've used in the past: CALCULIX/NETGEN, CATIA GPS/GAS/ANL, OpenFOAM (flow), COMSOL (magnetics/heat transfer/flow), ANSYS(mechanical/thermal/CFX) (it seems that i'm an old man) - but I've never heard VisualFEA before? What is the reason/advantage to choose this tool?

Hello Martin,
I've made 2 additional nodes (some bugs at the moment) CSV-File reader that evaluates points. You can select the columns individually in the node. The node can also read only numbers -> output a numarray. A second node idxReplace replaces values in a numarray by the index.

Here is a first result:



I will try to find the bugs in the next days and post an update of the node editor.

Have a nice day
Karsten

Hello Martin,

I've posted a modified version of the nodeeditor here http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.131 that maybe help you for a first step.

Have a nice weekend
Karsten

Hi Karsten and good morning.

Thanks a lot or your update! Now "Project Elephant" is going in a very promising direction.

Could you please post a practical example with a nod file and some csv files, in order to show us how to use the new CSV node ?

I post here an updated version of your "Project Elephant", the version v.0.85mod5

It's almost identical to your version but it has includes the "objectsExt.js" with the "SelectedObjExt" node that I wrote some times ago.

This node is an updated version of "Selected" node, that allows to specify the order of selected objects : "By Selection" or "By Creation".

It's very useful in order to obtain different elaborations of the same data.

Here's the archive : http://take.ms/Pxp6A

Have a nice day,

- Marco (mkdm)

Hello Pilou,

I don't have any plans to make a fork of the elephant - everything I made is an addition to Maxs untouched core development (I put it all together, because I think it is easier to handle for other users). And if Max change something important - I have to change the nodes - so I did it in the past.
I try also to understand Max philosophy and make it compatible to the planned workflow. It is possible that most of the nodes and solutions are someday obsolete - so it was in the past, but some ideas of me and others may help to get a better tool. I don't know if I can handle all that stuff - every help, every idea is welcome. I don't know why I try to create nodes - maybe just for fun, maybe it is exciting to see what is possible and what others try to do. I try to understand this tool and check the possibilities - If I would need a finished tool, I would buy grasshopper.

Everything is limited in general and my programming skill in special - my nodes don't have the quality or performance of Max ones, but you have always the freedom to play with them, or ignore them, or improve them, or make proposals for better solutions, create something with them, ....

Have a nice weekend
Karsten

p.s.:I switched back to this thread, because I don't want to confuse other users with my posts.

Hello Marco,

you can use the cat50x50.csv from libelle. Create the node and choose the file - thats it. Now you have a pointarray at the output. If you have a look in the Info you will understand how it works;-)
The node works with absolute path-names, so it would only confuse others, that only have a quick look in the nodefile. It's only a draft that has to be improved and I'm not an expert of file handling and parsing :-( If there are comment lines in the CSV-File you can choose a start phrase and an end phrase for start and end of evaluation the columns. You can switch to numarray to evaluate only one column. You choose the column by the number in one of the fields (starting with 0 for the first column) "-1" means no evaluation for pointarrays a default value will be set.

Have a nice weekend
Karsten

@ Karsten
Thx for the Infos!

So if I good understand now there is "2 big" one! :)
nodeeditor.v.0.85 (by Max)
nodeeditor.v.0.85mod5 (By mkdm & others ;)

Am I right ?

Does it possible to have a list of new nodes different (and their functions) than the native Elephant native ?

Hello Pilou,

here is a quick and dirty overview of all nodes - not complete, because for Marcos nodes, I have to take a second look - I know only the standard functionality.

Have a nice day
Karsten

Hi karsten.

I'm confident to find some free time tonight to update your xls with the infos of my nodes.

Thanks.

Hello Marco,

that would be fine, but let us switch back to another thread - here is a different focus!

Have a nice and productive evening
Karsten;-)

I totally agree with you.

Let me know.

Best,
