I need to compare the amount of liquid fraction in a solidification model at various time.
but I am confused, is is the time equal to the actual time or not??
need help
Usually the total time correspond to the time that the analysis has to run (most often the computer clock time) but it does not mean that it is the experimental time since your analysis parameters may have been defined with self consistent data. For example in Abaqus, there are no units as long as the system is consistent it is ok. So if you want to compare your numercial data with experimental, you should check that both are coherent. Hope this make sens.
Regards,
Ideally, Yes. This is the time of actual expt if there is no disturbance and other variables which you have not considered in your model. If you have not made very large assumptions then time of filling and solidification in your model is the actual time it will take during experiment.
Yes, the total time should be equal to summation of all time step size. i.e. if the solidification time is 5min then summation of all time step size should be 5min.
Thank you Pankaj for your answer.
But let me very clear about my problem, I need to observe the amount of material solidified after 5min in simulation i.e I have to run my simulation for 600 time steps if size of time step is 0.5 sec. Now I will go to my experimental setup and I will start my project for 5 min to check the validation of my result.
Is it okay or not???
If not okay, is there factor or something like that to modified the simulation time to make equivalent with real experimental time?
Thank you again.
