<div dir="ltr">Hi Maksim,<div><br></div><div>I think you still have a choice between the various slope limiters in conjunction with upwind TVD (but cf. the user manual). The hybrid slope limiter is nicer for accuracy but I think minmod is the most diffusive so the best for numerical stability.</div><div><br></div><div>Best,<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr">--------<div>Ryan</div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, May 10, 2021 at 5:05 AM Maksim Kozlov <<a href="mailto:maksim.kozlov@nu.edu.kz">maksim.kozlov@nu.edu.kz</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr">Dear flash users,<div>I am using the upwind TVD method to reduce numerical oscillations near discontinuities. I have set the runtime parameter useTVD=.true. and specified +supportPPMUpwind and -nxb=16 in setup. The only thing that is unclear to me is the value of the slopeLimiter runtime parameter that I should set to use upwind TVD. Is it "hybrid"?</div><div>Thank you!</div><div>Maksim</div></div></div>
