I have an upcoming meeting and amazingly they are still using Zoom to host it. I know there are safety issues with the site, so how can I best protect my machine after this meeting is over?

Every day this program reminds me just how awful this software can be.

Today's problem is I have a tube and I am trying to define a force in a direction parallel to a face. ANSYS typically defines the direction perpendicular to a face, but I don't have any faces that are perpendicular to the direction I want.

I could also settle for assigning the direction along the X or Z axis, but I can't figure out how to do this.

Something that should be so basic as this, should not require posting a question online.

So I have a cylindrical vessel with and inlet and outlet on opposites sides of the model on the curved side. Looks like a turbocharger on a car with the inlet on one end inducing a swirling action of the air.

Particles are being shot into the flat end of this cylinder at a certain rate and swirling around and around until they exit the other side. I have the material at 200C. The air inside the vessel is about 25C and the inlet volume flow of air is also at 25C.

When I run the sim, I can see the particles flying out and they look correct. I can see their velocity and that looks correct as well. I can change the overall dimensions of the vessel and they particles and flow trajector

Adding a little mid century style to the inside of a home is a lot easier. Some mid century furniture or color schemes go a long way to give you that vibe.

But what about to the outside of a non mid century house? My house is about 100 years old but was redone a few years ago. It doesn't have a mid century look at all, but I really love the mid century aesthetic.

And for those who might be wondering, MMC homes are few and far between in thsi region, so even if it was an option to move into one, actually finding one could be tough.

Per the Depot site, it is made according to ASTM A733 specifications, but to read those, it looks like ASTM charges you (according to their website).

I have a DIY project where straightness is important and I would like to use some of this pipe, but I'd be curious what kind of tolerance these pipes are made to. Specifically interested in concentricity and straightness of the pipe. I have a roughly 18" long piece but since I am working from home I don't have access to any of the indicators in QC we have at work to see how straight it is. Also this particular DIY

Road are empty right now but our infrastructure is still in shambles. Construction work tends to not be a particularly close-contact job.

We should use this opportunity to do repairs that we need to do anyways. This way it's not even a big deal if 1/2 the lanes of a highway are shut down. Few people are driving, so you're not going to cause major backups.

Watching an older episode of Roadkill where they go rallycrossing at an SCCA event and they got totally lost on the course. I recall going to one many years back and feeling lost as all hell as well even after walking the course. I get that chalking up the course might be a pain, and so would putting up more cones, but clearly getting lost in a course is common enough where you'd think they could do a better job at it.
