ulimit -n command shows no change inspite of modifying the /etc/security/limits.conf file

While compiling peridigm, I am facing the following error.

/usr/bin/ld: cannot find /usr/local/bin/trilinos-12.12.1/lib/libgaleri-xpetra.a: Too many open files/usr/bin/ld: cannot find /usr/local/bin/trilinos-12.12.1/lib/libgaleri-epetra.a: Too many open files/usr/bin/ld: cannot find /usr/local/bin/trilinos-12.12.1/lib/libaztecoo.a: Too many open files/usr/bin/ld: cannot find /usr/local/bin/trilinos-12.12.1/lib/libisorropia.a: Too many open files.../usr/bin/ld: cannot find /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crtn.o: Too many open filescollect2: error: ld returned 1 exit statussrc/io/mesh_input/quick_grid/unit_test/CMakeFiles/ut_QuickGrid_solidCylinder_np1.dir/build.make:1465: recipe for target 'src/io/mesh_input/quick_grid/unit_test/ut_QuickGrid_solidCylinder_np1' failedmake[2]: *** [src/io/mesh_input/quick_grid/unit_test/ut_QuickGrid_solidCylinder_np1] Error 1CMakeFiles/Makefile2:1009: recipe for target 'src/io/mesh_input/quick_grid/unit_test/CMakeFiles/ut_QuickGrid_solidCylinder_np1.dir/all' failedmake[1]: *** [src/io/mesh_input/quick_grid/unit_test/CMakeFiles/ut_QuickGrid_solidCylinder_np1.dir/all] Error 2..[ 58%] Linking CXX static library libPeridigmLib.a[ 58%] Built target PeridigmLibMakefile:138: recipe for target 'all' failedmake: *** [all] Error 2

I used the instructions in link to increase the soft and hard limit of the processes by using the following:

#@student        -       maxlogins       4* hard nofile 97816* soft nofile 97816session required pam_limits.so# End of file

However, even after restarting the wsl terminal after updating the limit.conf file as instructed in the link, the ulimit -n still shows 1024 instead of the modified value. Why is it not changing? Any advice?

I am using Windows Subsystem for Linux Ubuntu 16.04.
