However, when I write<br>
<br>
-ts_ssp_type rk53</div></blockquote><div><br></div><div>Therefore, this is not even close to being valid. What are you trying to do? Get 5 work stages? You can see other ssp options with the -h option (probably helps to pipe the output to 'grep'),</div>
<div><br></div><div>./program -ts_type ssp -h | grep ssp</div><div> -ts_type <beuler>: TS method (one of) euler beuler cn pseudo gl ssp theta alpha</div><div> -ts_ssp_type <rk104>: Type of SSP method (one of) rks2 rks3 rk104 (TSSSPSetType)</div>
<div> -ts_ssp_nstages <5>: Number of stages (TSSSPSetNumStages)</div><div><br></div><div>So, you would probably want the following options,</div><div><br></div><div>./program -ts_type ssp -ts_ssp_type rks3 -ts_ssp_nstages 5</div>
<div><br></div><div>but keep in mind that 5 is the default for -ts_ssp_nstages.</div><div><br></div><div>Hope that helps.</div><div><br></div><div>Sean</div></div>
