Dear Friends,

I have written a UEL for Strain Gradient Plasticity and is working well when i give Boundary condition as Concentrated force, But when i apply displacement boundary condition the it leads to 'system error 144'.

Iknow that system error 144 corresponds to division by zero or infinity, but then why it is coming in on displacement boundary condition is i am worried about.

I will be extremely helpful to anybody for any type of help on above problem.

Thanking you in advance

A postdoctoral fellow (PDF) is sought to develop novel simulation methods for carbon sequestration problems. Working within the Earth Sciences and Civil & Environmental Engineering departments at the University of Waterloo, this position will be part of a wider multi-university research program on the risk assessment and management of carbon capture and storage in a Canadian context.   The initial contract for the position will be for one year, with the potential for an extension up to three years.

Hi All,

I have a problem of solving an axially moving beam nested within a stationary, simple supported envelope beam using ProMechanica. If anyone knows how to deal such problem in ProMechanica or any other FEM software it will be a really great help. I am trying to describe the problem in details.

Hi All,

I am trying to simulate tooth deformation. It involves that the density of tooth changes with deformation. I want to know is it possible to define density as a solution dependent variable in VUMAT?

 Thank you in advance!
