    Help running abaqus explicit dynamic analysis

    Is it possible to view the sph in visualization like a smooth contour (CEL) or extrapolate between spheres to make it look like a contour map?

    Help running abaqus explicit dynamic analysis

    I forgot to attach the input file in the first thread..https://files.engineering.com/getfile.aspx?folder=f0bf020a-33bc-4259-b099-8984840278bd&file=timsph.inp

    Help running abaqus explicit dynamic analysis

    Thanks for your help FEA way, would you be able to check my input file please? I am using SPH to model the liquid like substance. Could it be that there are too many spheres? The elements have similar time increment. *Material, name=DIE *Density 2.3e-09, *Elastic 131000., 0.3 *Expansion...

    Help running abaqus explicit dynamic analysis

    Hello. Can someone check my model and see what I am doing wrong? I basically have a rigid body at the top, liquid like material in the middle and a deformable body subjected to bending in the z direction. The model is simple but it just won't run at all and is stuck at time 0. I get errors...

    How to characterise liquid based non curing grease or gel type thermal interface material TIM

    Hello engineers. I really need your advice on my research. I am trying to investigate the possibility of application of liquid based (gel or grease) non curing thermal interface material (TIM) for thermal management of electronics such as pcb, ap, etc. The material would probably have a low...

    Welded pressure vessel operating limit

    Sorry but my question wasn't regarding the welding process. Could you please let me know if you have some idea about pressure testing as written in post? I want to know what to do after the welding.

    Welded pressure vessel operating limit

    I have modelled the welding process (laser using dflux subroutine with a gaussian distribution) via 3D uncoupled thermal mechanical model with uniaxial true tensile properties incl. elastic, plastic (annealing temp), and other thermal properties with thermal and mechanical bcs. Once I simulate...

    Welded pressure vessel operating limit

    Hello. I have a thin flat square shaped container that is welded around the edges and filled with water. After welding it induces tensile residual stress approaching the material's yield strength around the weld seam. When I pressurise the vessel to more than 2 bar, what is going to happen...

    MPC and USDFLD or UFIELD

    I am trying to initially constrain my model using MPC and then release node by node when the field variable switches from 0 to 1. In the odb file I can see the FV changing from 0 to 1 but I am not sure how to use the field in the mpc subroutine. In the subroutine mpc then field looks different...

    Connector Element using USDFLD time variation help please

    Dear Mustaine3, Thank you so much for your advice. I wasn't aware of the difference between USDLFD and UFIELD. Thanks.

    Connector Element using USDFLD time variation help please

    I can't seem to change field(1) of connector elements using coord or npt. is there any other way of changing the field(1) of each element at different positions with time?

    Connector Element using USDFLD time variation help please

    I am trying to change the stiffness of connector elements using USDFLD as a function of time and coordinate. When I run my model, it says no value for the connector elements for any output other than those available for these specific elements. I wanted to change the stiffness with increasing x...

    Subroutine within subroutine / global variable

    Hey All, I am running a weld model on ABAQUS using DFLUX subroutine and wanted to request HBF (heat body flux) as a field output . However, since Flux(1) cannot be requested as an output according to the documentation (surface and element based loading output variables do not include...
