This will be exactly the run I did on my laptop yesterday and completed without problems. Should you get an error on the number of blocks, retry to run with 8 MPI ranks. Do not use a different flash.par file so we are on the same page. Thanks!<br>

<br>
The MacLaurin test problem as it is currently in FLASH4 is outdated. It has not been updated with the many changes that occured during the last 3 years. The MacLaurin unit test is the one that has been designed and used for checking all new multipole ideas. It's main purpose for creation was to get rid of all the other developments in eos, hydro, etc...that happened in parallel and which could cause interference with the sole testing of the multipole routines. The MacLaurin unit test uses a customized driver routine that has been stripped off all the unnecessary parts (like eos and hydro for example).<br>
<br>
Hope this helps,<br>

Hello FLASH users,<br>
<br>
I'm trying to set up the Maclaurin test problem and it doesn't appear to work. In particular, it appears that it is failing on calling the equation of state, which is strange because it is just an adiabatic gamma-law EOS. On the other hand, the unitTest/Multipole seems to work just fine. Because they are so similar, it is confusing why this is happening, but it appears that the difference is that the evolution step in the unitTest is empty, i.e., no hydro step, while the Maclaurin uses the hydro step. This suggests to me that the included Maclaurin test problem no longer works, i.e., these Maclaurin test problem does not evolve. Is this correct?<br>
<br>
Cheers,<br>
Phil<br>
