Hi all,<div><br></div><div>So I am running simulations which have many time steps and normally I would save the files as .pvd via outfile &lt;&lt; File(...). This creates a new file for each time level</div><div><br></div><div>However, if I need to solve a large geochemistry system of equations (~20 unknowns) over 100+ time steps, I would prefer not to have 2000+ pvd files sitting my file system/laptop. Is there a way to store the solution of all time levels into a single file?</div><div><br></div><div>Thanks,</div><div>Justin</div>
