Is your Base Point correct? When you click a point as Base Point selection there should be Point ID displayed in X Y Z fields, not some values.

Hi, You have two options. 1. Go to Analyses > Nonlinear > Edit > Click Next until you reach Nonlinear Control Options > Set Time Steps (ex.100) > Set Time increment (ex. 0,01). > Output Controll (if needed) > 3..ALL 2. Create ramp function vs. Time. and use it in your pressure definition. Acc...

Hi, I would like to run a calculation with element rupture. This will be Advanced Nonlinear static. The easiest example I could imagine is a flat bar with reduced section in the middle. Looks like this below: ______ _______ | \/ |--> |______/\_______|--> This is a plate model...

Hi, I need your help to design compression only support. I need to constrain one surface like below: T X - free T Y - free T -Z - fixed (no penetration is allowed) T +Z - free (separation is allowed) R X - fixed R Y - fixed R Z - free I have only one body (no contacts). Please help...

Hi jacksonfem, I'm not an expert but the wired element shape from secend picture in your post happened to me before. Usually the reason was too coarse mesh. With smaller elements it was fixed. Have you tried this already?

Hi, I have large solid model with 7 multiple surface contact points - friction 0,1. Model was calculated with static structural analysis. LGDISP are on. Now I would like to double check the results with nonliniar static. I can choose between 106 and advanced 601. What I need to change in my...

Solved. For anyone interested. You go to F6>PostProcessing>Contour/Criteria Levels>3.User Defined then Click Auto Max Min to keep those values then Go to Set Levels and under level 2 type desired threshold. Apply. Done!

Dear Blas, And can you display you max stress value on top of the contour legend as well? See attached. Indeed I want to color all elements above treshold to red, but I want to keep my max stress value there on top. Then it is clear what is the max, and what is above the limit I have set. I...

Hi, you might need to better describe what load case you want to analyze: geometry, loads, constraints and what kind of result you expect.

In my opinion overlapping elements will not add extra stiffness. They may generate extra enormous stress as Nastran will see one face pressed into the second.

Hi guys, Please help. I want all elements with stress higher than 150MPa to be displayed in red. I go to View Options > PostProcessing > Contur/Criteria Levels. In Level Mode I go to User Defined. In Contour Palette I go to User Palette. #of Levels I like to keep 16. I want to keep original...

Thank you crostolo, but I see my approach is completely wrong. I see having 1D and 2D elements in connection is not a good idea for checking what is the situation at connection area. Look picture attached. My RBE2 spider is too small. Would be better to select the nodes that are close to the...

Damn!!! Double click to refresh! That what I was missing all the time :) Thank you crostolo.

Blas, thanks a lot for your big reply! But I stil can't do what I want. Let's start simple example. 1. I have drawn in femap a surface 100x100 on plane XY (Z=0) 2. In properties I say thickness is 10mm 3. Surface is meshed and the thickness is distributed equally: 5mm to -Z and 5mm to +Z. I...

thread1234-338079 Hi all, I therad mentioned above the connection 1D beam to 2D plate is done by RBE2 element. But if end of my beam element is touching my plate element can I force Femap to have coincident node there and no RBE2 connection? Just like when I have 2 beam elements at 90 degrees...

I understand that there are existing some factors that are not included in FEM model. I guess you can not simulate material imperfectness successfully. But like I said I was interested for example in mesh quality influence on calculation result assuming my loads, connections and constraintes are...

Hi Thomas, True that element type must be suitable for particular geometry. Regarding "beam elements are most precise, shell elements are medium and solid elements are giving biggest error in calculation." I have heard that 1-D elements definition fits the best in the solution matrix. With 2-D...

Hi guys, Once somebody asked me a question: what is the error of your calculation? How should I answer? -I know error depends on elements: beam elements are most precise, shell elements are medium and solid elements are giving biggest error in calculation. -For sure error depends on mesh...

Non an option for tet. Too heavy model, too weak machines. I'm sorry. I will explain better my question. Please forget the mess above. 1. I have solid model. 2. I do midsurface extraction. 3. Before meshing I create default Properties with no thickness assigned inside - there is 0 4. I mesh it...

Hi there, 1. I'm using this function as in video here (https://www.youtube.com/watch?v=n2Hc7onzk_k&index=3&list=PL1m1vu8_quoB_Eo2aGL2dpYXs2AQG9OXV) to automatically get surface thickness from my solid model. But of course Femap is not always perfect. Can I correct the result somehow? I can't...
