numpy? I guess this is for comparing mathematical functions one by one, not for testing Yade. There is sometimes this little detail that nobody suspect and which makes things go bad.
In order to really test yade, we would need to run some typical simulations and check that the results are the same. This is really hard to do, because we know the results _will not_ be the same actually. So, it would need to analyze statistics of results after repeated runs and see if the statistic is the same, or find something that is obviously incorrect from a physical point of view (the bug I just filled on instabilities is an example). Moreover, if we don't find the "good" simulation exhibiting the problem, it can remain hidden for some time. For basic triaxial tests, I can tell results are at the same time realistic and in good agreement with previous results. Luc mentionned a possible problem in cohesive laws however, no idea if it is related to eigen yet. I don't think we have manpower and time to do such hard testing before next release. So, we can drop wm3 completely now (lazy but risky), or keep both library support for some time (painfull but safe), so that if strange results are obtained we can always test wm3 build vs. eigen build. Also if one guy needs last minute results before PhD defense, and find that his code behaves strangely when compiled with eigen, I'm sure he will be glad to switch to wm3... Keeping wm3 until the next release should not be that hard, is it? We can perhaps quit typing wm3-friendly code after that? -- r2247 broke compilation with wm3 https://bugs.launchpad.net/bugs/585141 You received this bug notification because you are a member of Yade developers, which is subscribed to Yade.
