Dear Worcester, FEMAP geometry engine is based in Parasolid, is the native format, then if you want the maximum precission in geometry use Parasolid (*.X_T files), but STEP is a valid "neutral" geometry format very useful to share solids, I never have had any problem sharing or importing...

Dear Worcester, I have tested the issue but at my end FEMAP is running correctly, so is a local problem related with your geometry, probably you have in your FEMAP model a mix of solid parts with different scale factors, list your solids using command LIST > GEOMETRY > SOLIDS, you will see...

Dear Tom, To help you more effectively you need to explain better the problem: How do you generate the EXCEL file, using an user API or a FEMAP command?. When you say FORCE BALANCE you refer to create a FREE BODY DIAGRAM?. In this case you need to make sure to activate the FORCE BALANCE in the...

Dear Standley, The text results are pinted in the nastran *.f06 file, is this the file you are referring to?. Never use the SCRATCH directory to save results, this is only for NASTRAN for temporal location during calculation, after solving with success NASTRAN will delete temporal results...

Dear Matt, For SPOT WELDS we are fortunate using Simcenter NASTRAN where we have the CWELD element, see my blog. In FEMAP is ALL automatic using the CUSTOM TOOL APIs, simply define a TXT file with the spot welds XYZ locations and you are done. In NX I suppose you have automatic methods as well...

Dear hhcc_im, I ran your FEMAP model and the analysis runs correctly, why you say "I cannot get the same full non-lienar analysis rersults"??. You need to play with "Actual Deformation = ON" and "Scale Deformation = 1" to see nonlinear displacements results at scale 1:1 (real scale deformed...

Dear Itxusta, As told by SWCOMSITES you need to assign a cylindrical coordenate system (either local or global) to the properties of the CBUSH element. This is the form we have in FEMAP with NASTRAN software bundle to define the properties of the CBUSH element, search for similar fields in NX...

Hello!, But RBE2 elements moves like a rigid element, the coordinates are not updated in a nonlinear analysis (SOL106), this is the main limitation with SOL106. The modern Nastran Multi-Step NonLinear (SOL401) support RBE2 elements for large displacements effect, updating it coordinates during...

Dear Arca, Damping is neglected by default for eigenvalue analysis (SOL103), the only way to account for damping is to include explicit dampers elements, like CBUSH elements. Best regards, Blas. ~~~~~~~~~~~~~~~~~~~~~~ Blas Molero Hidalgo Ingeniero Industrial Director IBERISA 48004 BILBAO...

Bad, very bad meshing approach. RBE2 elements should be used as the very last resource. BASIC NONLINEAR (SOL106) is part of BASIC NASTRAN, then is included in your license. By the way, Glue effect is not supported in nonlinear analysis (SOL106): ^^^USER FATAL MESSAGE (IFPS) ^^^FOR SOL...

Dear Mark, Do not get creazy, the beter method to joint shell to solid is simply edge-to-face GLUE effect, forget skining, see my blog: https://iberisa.wordpress.com/2011/08/21/contacto-rigido-curva-a-superficie-glue-edge-to-surface-contact-por-jim-bernard-siemens-plm/ Glue is a simple and...

Hello!, Explore the CUTOM TOOLS > POSTPROCESSING, you have a lot of APIs: Also in FEMAP V2401 you can compute automatically vonMises stress for bolts meshed with CBEAM elements: MODEL > OUTPUT > COMPUTED VECTORS Best regards, Blas. ~~~~~~~~~~~~~~~~~~~~~~ Blas Molero Hidalgo Ingeniero...

Dear Ian, I got it!!. In fact, if I delete ALL POINTS the mesher runs OK. I will explain: In the model if you do a ZOOM OUT you will see points in the screen, separated by a distance around 12000 mm. This is the problem: as told, the FEMAP mesher takes in consideration the MERGE TOLERANCE, a...

Dear Ian, I guess this is a problem related with model dimmensions or internal tolerances, without the <FULL> FEMAP model in hand is not possible to say more, but check the following: • I strongly suggest to work always in millimeters to avoid meshing problems related with tolerances: is...

Dear Jeff, Reverse the order, we have the same command in FEMAP "Mesh > Connect> Closest Link" and the key is to include in the set "FROM" all the nodes that will have a GAP element for sure and in the other set "TO" the rest of nodes, the command will choose the "nearest" node. This is a useful...

Dear SWCOMPOSITES, I forgot to mention the limitations of the CWELD NASTRAN connector: • BOLT PRELOAD: yes, this is an important limitation. In reality, all bolting joints are preloaded, then you can imagine. But the CWELD connector is of inmediate application, easy to mesh, fast, thanks to the...

Ah!, regarding postprocessing stress results: • Nodal stress in solid elements: if the mesh density is correct (not coarse or highly distorted) the nodal stress is a correct result. But please have in mind: if the node location is singular, not matter you refine your mesh the nodal stress will...

Sea EC, As SWComposites says, how to define bolt connections this is the ethernal question, always the same problem. The API on CUSTOM TOOLS > MESHING > HOLE-TO-HOLE FASTERNER do the job using a CBEAM element with the bolt cross section and a spider rigid RBE2 with rotational DOF OFF for head &...

Hello!, Check the FEMAP version, modern versions like V2401 are really robust when dealing with geometry. In any case, don't worry in excess: after extending all surfaces run command GEOMETRY > SOLID > CLEANUP and FEMAP will remove all etra points. Alternatively, in the MESHING TOOLBOX > FEATURE...

Hello!, Yes, the PATTERN approach is present in many commands in FEMAP: You can mesh the geometry and when you copy the geometry you copy the mesh as well. Or you can copy, reflect, etc.. mesh and you can copy the associated geometry as well. Or you can copy the geometry with properties, and...
