Hi, Batch parameters csv file generated has delimiters which has "Sim_" codes in for each simulation based on the varying parameters. When I add more "sim_" codes for multiple simulations, keeping the original delimiter format, simulations run perfectly. But, as it is difficult to enter parameter values in this original format when the number of simulations to be done are high, I used "text to columns" or "import as a text file option" and easily entered the parameters. However, saving this file makes the csv file as "without delimiter" and the simulations do not go through. I saving it as another csv filename, but the simulations still do not run. How can I get around this? Is there any simple of way doing it in the original batch parameters csv file when there are many "sim_" code lines...? Please help.
