while carrying out a simple 2D analysis of welding of butt joint considering the source of constant heat flux and applying it at certain nodes as constant heat flux, i encountered a problem that it says that the temperature at particular node is exceeding the pre set limit and no solution is obtained. I am a freshman in Ansys so any help in this regard will be helpful

Hello,

As part of my PhD, I have to study the problem of the stability of the excavation face in tunnels driven in jointed/blocky rock masses. Therefore, I`m trying to build a 3d discontinuum model with 3dec. As I`m rather new to this code, I have a series of doubts (mainly concerning the way to reduce the size of the model and then the time needed for cutting the block geometry and running the calculation). 

I would be really glad if someone who knows the code could help me.

Thank you!

Andrea 

Any one can help me ,using ANSYS how to apply reversal loading in the RC Beam Column Joint at the end of the Beam node..

Thanks & regards

We have an equipment and technology for determination of residual stresses. They are based on the hole-drilling method and electron speckle
interferometry (ESPI-HD method).

Convergence of Numerical solution may depend on the conditionning of the problem's matrices.

An ill-conditionned matrix produce singulariy cases. This is due to bad shaped elements in

structural mechanics: nearly degenerated elements with zero area (in 2D) or zero volume (in 3D)

The conditionning can be analyzed by numerical algorithms or existing commands in order to

detect these problems.
