Understanding the time step increment in the transient model of fuel cell
Posted Oct 4, 2011, 11:00 AM EDT Batteries & Fuel Cells Version 4.1 1 Reply
I would like to introduce myself as a Graduate student working on fuel cells. I have made a transient fuel cell model with an sinusoidal voltage function as an input. I run the model at the initial state first in order to getIn the study 3 (transient) , i gave the starting point as 4.8, an interval of 0.25 secs and ending point as 15 seconds through range(4.8,0.25,15) with a tolerance of 0.05 .
The program ran successfully and gave me results. However, in the results , there are a lot of data points instead of the specific points 0.25 seconds apart. I am sending the excel sheet with all the specified data points (the left most column in the data sheet) on which the program is calculating the results. I want to attach the model but it is well beyond the attachment limit.
Can anyone explain me on what basis is the COMSOL software selecting the data points and how is it related to my input.
