It was defined in the interaction module - special - crack - create - counter integral. And then the following edge was selected: Another question arise: Am I correct, that the J-integral method uses the elements on each side of the crack node where the SIF is calcualted(the elements...

Hi, In Abaqus we can find the nodes belonging to the domains used to calculate the contour integral at the different contours. Abaqus documentation states: [highlight #FCE94F]The domain associated with each contour is calculated automatically. The nodes belonging to each domain can be printed...

I found the element number in a set using: set1 = mdb.models[model_name].rootAssembly.sets[set_name] # get the elements in the set elements_in_set1 = set1.elements elem_number_set1 = np.size(elements_in_set1)

I can use the tools-query-mesh to display number of elements in a region/cell. But it doesnt record in macro. Is there a way to obtain element number at a certain cell-set using scripting? Then I can just loop until I get the desired element number in the cells between the partitions for the...

Hi FEA way, thanks again for your help. Additional partitions perpendicular is a great idea, but however very hard to script and hard make parametric for irregular spline geometries. I dont think seeds with size control will work. Then the outer contours will have more seeds than the inner...

As add on, here is a mesh where I seeded the cells:

Thanks, I actually did not try that. But it seems that it still applied seeds at the edges when selecting cells. This, again, results in the elements between the edges splitting up into more elements than desired. Even when I use the constraint "Do not allow the number of elements to change". So...

Hi, I am currently working on creating a model for the contour integral calculation of an arbitrary internal crack using Abaqus scripting. However, I have encountered a problem with my mesh at the crack contours, where regions with unstructured elements (as seen in Figure 1) create noise in the...

Hi I need to install shapely in abaqus python. I tried copying the shapely installation files from my anaconda environment to the abaqus site_packages folder, but I doesnt work. When running my script in abaqus, it says "ImportError: No module named lib". Does anyone know how to install python...

Hi FEA way, thanks again for your help. Query output seems fine: Total number of nodes: 279995 Total number of elements: 67160 67160 quadratic hexahedral elements of type C3D20 And when using wireframe display with interior elements included, it looks correct.

Hi I have meshed a cylinder in abaqus using quadratic hex sweep mesh. The cylinder which is partitioned, is seen on the following figure. The 4 outer cells are meshed using medial axis, and the rest are meshed using advancing front. I then use the visualization module to see how the mesh...

Thats right. Actually, both methods would be relevant.

I just found python code from Github calculating the minimum boundary box using provided points. So if not possible in sketch module, I will implement the algorithm to the node points.

Hi, Does anyone know a method where it is possible to get a minimum bounding rectangle/box from a closed region in sketch. I have to collect geometrical parameters of closed irregular regions, and therefore the minimum bounding box width and length are important. If not possible in sketch...

Just found this information on the Abaqus documentation website: "If a part was created by sweeping a cross-section along a sweep path that is composed of a closed spline, the resulting part is meshable only if it is split into two or more regions."...
