Dear Nek team,
<div><br>
</div>
<div>I have a quick question: in cvode_driver.f, in the routine fcvfun, do all the derivatives must be in weak formulation (using wgradm1) when constructing the right hand side term ydot?</div>
<div>Because at the end of the routine fcvfun, dssum and multiplication by binvm1 are applied to the right hand side term ydot.</div>
<div><br>
</div>
<div>It’s also not clear to me if I need to apply dssum and binvm1 for each derivative term appearing in my equation (in other terms, each time after calling wgradm1), or if I need to apply dssum and binvm1 only to the whole RHS term ydot ?</div>
<div><br>
</div>
<div>I’m afraid of inconsistency if apply twice dssum and binvm1: one during the construction of operators and one on the final ydot term.</div>
<div><br>
</div>
<div>Thank you for you help !</div>
