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...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

Does Napabucasin soluble in dichloromethane and in ethanol?

I need to prepare a solution of Napabucasin (inhibitor of cancer cell stemness) in dichloromethane. The drug is expensive, so maybe somebody already tried to do it. If it is soluble, what is the...

Can we distinguish the type of free fluid inside the pelvic and abdominal cavities whether blood or serous fluid using the ultrasound?

during ultrasound examination of acute abdomen, sometimes we see free fluid , can we know the type of fluid ,whether blood or not , using ultrasound only? if yes , what are the sonographic...

I assume your problem does not concern a heated flow with phase-change. However the following document about a flow with phase-change provides expressions for quality (gas to liquid ratio) and slippage between phases which could provide the basis for an expression to calculate bubble residence time.

Thanks for that. Interesting breakdown of flow regimes.
