What's the Optimal Shape Function for Phase Field Simulations in FEM?

AI Thread Summary
The discussion focuses on identifying the optimal shape function or element for phase field simulations in finite element methods (FEM). Participants emphasize the importance of experimenting with different element types, as benchmarks for this specific analysis may be scarce. The conversation highlights the need for practical comparisons of results from various shapes used in simulations. Users are encouraged to share their findings and experiences with different shape functions. Ultimately, the goal is to determine the most effective approach for phase field simulations in FEM.

What have you found so far? What shapes are typically used for which types of simulations?

If you can't find any benchmarks for this type of analysis, it would be best to just try different element types and compare the results (i.e. do the benchmark yourself).

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
