Nick. The editor may just be natural talent. :) Check the cursor is top left of the reply panel too, the "not quite loaded" state puts it in the middle and then formatting tends to be creative.Â
Sakun. Turning on/off Pseudo Transient just switches between setting a Courant Number (default is 200, 1 is far too low, 50-100 is usually reliable) and a time factor (set in the Iterate panel, 1 may be optimistic, 0.01 is far too low for most models). The option is good, and the benefit is briefly covered on the page you posted; all the maths is in the Theory guide and possibly in any references given there.
Strictly speaking, posting DOC pages is on the "don't do" list, but as it's not showing any equations or model specifics I'll leave it: just an informal comment.Â
