Hello, I am simulating a wire by applying rotation at one end and fixed at other end. I applied rotation using boundary conditions, may I know how to find rotational force required to rotate the wire from output. Since force depends on material properties so I guess there might be formula for...

Hello, I am simulating a 12 filar and 9 filar wire torsion test. I can see contact stress values even after 30 degress in 12 filar where pitch distance is more but contact stress in 9 filar even after 180 degrees rotation is zero. I am analysing using abaqus with 1D element model and I use...

Hello, Upon execution we provided crank bar length as 0.25 L for slab instead of 0.15 L as per IS456 . May I know the consequences for this mistake and how to resolve it? The slab is for residential building.

Hello all, I am trying to do torsion test where the wire breaks after certain rotations. I noticed that whenever I model for damage with damage criterion values, I am seeing rotational moment values as zero but not for plastic modelling (only with plastic values and no damage values) . Is there...

Hello, I have designed 2 storey building but rebar size varies for columns at 4 corners.. bottom storey rebar area size is 700 mm2 and top storey rebar area size is around 1464 mm2. So am I doing anything wrong or results are acceptable?

Hello, I am designing flat slab for G+2 college building. The area is 12 x 25 metres and is it possible to design flat slab by providing column only at edges but not in the middle? I designed using staad pro by giving columns at edges and deflection is within allowable limits (DL + LL) so...

Hello, I am trying to calculate simply supported 1D beam with fixed end on both sides subjected to U.D.L. Now according to analytical formula stress = M/Z , where M = Wl^2/12 at suppports and M = Wl^2/24 in middle and Z = bh^2/6 in case of elasticity and Z = bh^2/4 in case of plasticity for...

Hello Abaqus users, I am trying to learn how Abaqus calculates plastic strain when cantilever beam is subjected to transverse load at the tip. For axial load it can be predicted from displacement but for transverse load due to bending of beam due to point load at tip it seems different. My...

Hello Abaqus users, Does anyone know how Δt in Abaqus explicit is calculated?. I tried Δt = l/c but that is stable increment. I would like to know how velocity is calculated in Abaqus explicit so I need Δt values . I even added screenshot of the formula. If it is based on natural frequency then...

Hello, I am experimenting with non linear cantilever beam with axial point load at tip where stress levels decrease after reaching plasticity. You can see as follows Yield stress------------- plastic strain 210000000------------- 0 232300000------------- 0.00884475 255000000-------------...

Hello, My abaqus is running very slow for past 2 days. Even when I try to model wireframe in part module, it takes approximately 5 seconds when I try to draw a line, for example, I click 'create lines: connected' the cursor arrow circles for 5 seconds, then I proceed to draw line by clicking on...

Hello, I am trying to crash two simple surface to wall and these two flat surface are coupled to a reference point which is in the middle of these two surface where there is a gap and when I apply translation to reference point, it is not moving or moving very small like 0.00001 metres. Also...

Hello, Am trying to rotate turbine using abaqus cfd and abaqus explicit by using co-simulation. I read that Abaqus CFD does deforming mesh analysis using an arbitrary Lagrangian Eulerian (ALE) description of the equations of motion, heat transfer, and turbulent transport. But I could not find...

Hello, I am still learning Abaqus. I like to know whether its possible to design sliding mesh or dynamic mesh in Abaqus CFD or its possible only with Fluent interface?

Hello, I have been running co simulation in abaqus of a rotor but after running for about 0.8 seconds where the analysis take about 12 hours it shuts down showing error like memory problem with warning window popping up. I am using 64 bit system with 8 GB RAM and I have plenty of memory. The...

Hello, I have modelled a wind turbine and like to rotate it through wind force using CFD. In the beginning I made a model in CFD with walls, inlet outlet and other things and also made fluid surface interaction with wind blade in elastic model. The software am using is Abaqus. The thing it...

Hello, I am trying to rotate the wind turbine by wind force so I used air properties as inlet in CFD but when in coexecution with CFD and elastic body, the blade rotates to around 15 degrees and it shows error. Later I learned I have to create boundary wall in CFD for allowing rotation for mesh...

Hello, I tried to increase frame rates by increasing n time increments to 8 from 1 where my total time for analysis is 8 secs. But the strain and stress curves are more curved (obtained from XY data) when the frame rates are increased (more than 1) and its linear when there is only one frame...
