I can't run MODFLOW Model using PEST in Visual MODFLOW Flex 4.1, and i can't find the tools PESTCHEK.EXE and INSCHEK.EXE in the PEST distribution files to run the model , Is there any help, please ?
You can download the latest PEST version from the PEST - web page (http://www.pesthomepage.org/Downloads.php). The zip - file includes the PESTCHEK.exe as well as the INSCHEK.exe.
