Thank you, I deleted a few bad elements and it ran fine.

Hi all, Is there a way to export contact forces to a text file? I can PRNSOL the nodal solution and multiply it by the area; but, it is off by an order of magnitude. I have 48 bolts and 10 load cases; so...it would be really nice. Any suggestiongs would be appreciated. Mark

Hi all, I have inheritied a linear static patran 2004 database with lots of pins, beams, shells and solids and I am trying to run in Nastran 2004. The analyis fails with the "NO PARAM values were set in control file." Any idea what this might be from. Thanks Mark

just got your post, sorry "ue" is my abbreviation of micro strain. Yes, on my test model, I had the interference modeled in; ie., overlapping surfaces. On my large model, which has ~25 contact surfaces and four press-fit bushings, I have been getting problems w/ convergence. I've been using...

Ok, I think that I got it to work.... contact pair, interaction, name, small sliding slave surf, master surf surface interaction, name, surface behavior, pressure over closesure=hard contact interference, amplitude=name, op new, type contact pair slave surf, master surf, -.xxx, _, _,_ This...

Hi All, How do you model an interference fit in abaqus standard? I have a bushing pressed into a plate--pretty simple, tet 4 elements (once I get it running midnodes will be added). Contact surfaces have been created from the element faces, normals checked. Contact pairs created...

Anybody know where can I find this subroutine? Thanks, Mark

hmmm.. not quite sure how to navigate through this FE Module, (looks like the old ansys to me). Just looking at the mesh properties in under the simulation tab indicates that "Element midside nodes" are "kept". This tells me what I need to know. Thanks

Hi all. I hava a very basic question about ANSYS 11.0. How do you tell if your elements have mid nodes? I did not do the model and it was meshed as a "hex dominant" mesh. I am comparing this model w/. I under stand that ANSYS plots results based on the "integration points of the elements"...

Ok, I got-it. I was not in the master rep.

Hi all, Anyone have any ideas on why I am not able to restructure a model. ie., -normal assembly -hardware installed in assembly -subassembly added -trying to restructure hardware into new subassembly; but the "restructure" feature is greyed out. Thanks, Mark

Hi All, I am new to ANSYS Classic FEA and have a simple question. If I have "scripted" in a few beams w/ beam releases etc, how can I view the loads in these beams/nodes? They are BEAM44 elements and I have keyopt (6) set to 1; ie., Printout member forces and moments in the element coordinate...

Thanks Mloew. I have reposted it there. I am thinking that this could also be a Patran question. The Patran model may be 15-20% high; however, missing midnodes in the Hyperview model makes me suspect Hyperview. Thanks, Mark

I am starting to use Hyperview to present Nastran results which works great. HOWEVER, several of my models have Tet 10 elements and the mid nodes from these elements do not appear to be in the Hyperview model. Since it is just for viewing, this is probably ok; but if I query the results on the...

I am starting to use Hyperview to present Nastran results which works great. HOWEVER, several of my models are have Tet 10 elements and the mid nodes from these elements are not showing up in Hyperview. In fact, if I query the results of the nodes that do come through, the the strain is 15 to...

Yes, I agree, shownin dimensions is the best way to do it; but in some cases; castings w/ complex geometry, or large assemblies, a dimension here and there is required. (I agree this can be fixed w/ some remodeling; but, sometimes the remodeling can be quite extensive. To "show" these...

Hi All, I have a customer who requests that all the dimensions be shown in the drawing and not added at the drawing level. Which is fine for most parts and it is nice for our customer to be able to change a part dimension from the drawing; however, often on castings or larger assembly...

Got-it. Thanks, Mark

Hi All, In ProE, how do you "loft" a surface. "Loft", I think is a Solid works function in which a suface could be created from a family of curves. I am kind of familiar w/ "Blend"; but I could not figure out how to use mutiple sketchs. Ok, second question. Does the search function on this...

I am not an expert; but this is what I do Create a cutting plane. For surfaces... Select the surface/Edit/Trim/ Select your cutting plane For solids... Highlight your cutting plane/Edit/Solidify and select which side to discard and save that file as part A and then do the same thing to...
