I plot U in function of T in a specific coordinate using "HISTORY", but i need to fix the maximum variation of U to 1. Please, do you have any idea about how to do it. Regards, Meryem |

You can set the range of a plot using RANGE or FIXED RANGE. i.e. HISTORY(U) AT (0.5,0) RANGE (0,1) The difference between the two is that FIXED RANGE will never change the plot range - it will just not plot data outside the range. Whereas RANGE will increase the plot range if the data goes outside the range - i.e will go back to automatic scaling if the data lies outside.

Since U is your variable, it is a field and possibly has a different value at each node. The only way to do what you ask, is to plot a HISTORY(U) as mentioned above and then read from the graph the value of T at which U was 0.5. This will give you the value of T for that point only. It may be different at another point in the domain. Or you could plot the HISTORY(GLOBALMAX(U)) which would give you the history of the maximum value of U at any node. (No AT clause is needed for this HISTORY since the parameter does not vary spatially).
