<p style="font-family: Calibri, Arial, Helvetica, sans-serif;">Based on these errors, I search in online for getting the solutions. According to some instructions, I reduced the <b>time_step = 4* Dx</b>. Also, I put the value, <b>w_damping = 1, feedback = 0 </b>and <b>damp_opt
= 1</b>. But again I am getting similar error messages after <b>05 minutes simulation</b> as follows. Please find the <b>NAMELIST.INPUT_02 and rsl.error.02</b> files for more detail information.</p>
