Sir, what is meant by spurious conservation laws and what are those quantities?

02 February 2016 0 10K Report

In lattice gas automata Head-on collisions conserve, in addition to total particle number, the difference of particle numbers in any pair of opposite directions. Thus, head-on collisions on a triangular lattice conserve a total of four scalar quantities. This means that in ad dition to mass and momentum conservation, there is a spurious conservation law.

Why does resource utilization of FPGA varies with respect to input size?

I have designed a serial input based matrix multiplier architecture on FPGA. For smaller matrix size[ like 4x4,8x8] the resource utilization is very minimal. But when the matrix size goes beyond...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
