Click on the FILE tab at the top left and select Options (bottom left). Solver is an Add-In so if you have not used Solver before you need to add it in to use it. Note that on the Data Analysis tab depicted below, one option is Solver. Note that we have requested to report just 2 divisions in the output for the time interval by using one of allowed formats for argument 6. To solve this problem numerically you will use the Add-In Solver. Next, we evaluate the array formula =PDSOLVE(B8, B2:B6, C8, D8,, to pass the spatial domain in argument 5, and the time domain in argument 6. See Output Format section for more detail. TCOL1 format is convenient to plot transient views of solution variables at a desired spatial locations. XCOL1 format is convenient to plot snapshots of solution variables at a desired time values. TCOL1 Column 1 of the result array will contain the output temporal points.A block of columns for the solution variables at each output spatial point will be reported in order following column 1. XCOL1 Column 1 of the results array will contain the output spatial points.A block of columns for the solution variables at each output temporal point will be reported in order following column 1. The allocated results array must have sufficient columns to hold output. include first and second derivatives ( u 1,x, u 2,x.),( u 1,xx, u 2,xx.) in output.
