the problem described by these equations is: at time=0, N particles are dropped onto an infinite plane to diffuse. C(r,t) represents the concentration density of particles
The solution is very simple, but I want to see the procedure.
Thank you very much!
Hi
When using contact print in abaqus, how it is possible to obtain contact press of slave surface nodes to the dat-file? It is easy to get the results of master surface nodes, but in this situation it is not possible to change slave surface to master surface.

I have modeled a beam column joint with steel and concrete by using 5 parts. Is it essential to give contact between the 5 parts?. How to give material properties for ordinary concrete and fibre concrete?. please help me that how to give reverse cyclic load in ABAQUS.
with regards

In this letter we obtain the finite-temperature structure
of 180^o domain walls in PbTiO_3 using a quasi-harmonic
lattice dynamics approach. We obtain the temperature dependence of
the atomic structure of domain walls from 0 K up to room
temperature. We also show that both Pb-centered and Ti-centered
180^o domain walls are thicker at room temperature; domain
wall thickness at T=300 K is about three times larger than that of
T=0 K. Our calculations show that Ti-centered domain walls have a
This month's issue of SIAM news had a beautiful story of how one hard problem in mathematics was solved in less than six weeks using online collaboration. SIAM's story is not online yet, but here is another link to the same story . SIAM news refers to a "super-mathematician" coming out of several individual mathematician spread all over the world.
