Hello everybody,
when I change some settings in the fluent during the solution such as turning off energy equation during the calculations, a dialogue box appears asking me whether I need to use setting changes for current calculations only or current and future calculations, I chose current and future calculations by default. Does that erase the previous calculations in energy equation or keep the results to be used in case of turning on the energy equation again. Frankly, I need to understand the difference between the two choices in the dialogue box. Thanks in advance.
