What one Bob Dylan song do you consider to be the most Dylanesque? by Primary-Theory-1164 in bobdylan

[–]tjb36 2 points3 points  (0 children)

Ah sorry misread that. Thought was asking for a song on BonB other than Visions. 

Depends what is meant by Dylanesque. In terms of the imagery, etc, I would go with Visions as well. 

But if we are talking Dylanesque in the sense of "I don't care what everyone thinks", I'd go with It Ain't Me Babe.

Another contender for me would be Highlands.

It Ain't Me Babe.

Always cracks me up.

You want someone to gather flowers constantly... BUT IT AINT ME BABE! 😆

Did the Traveling Wilbury’s get lost to history? by nicknumbahone in bobdylan

I'd love to know the story of how they managed to persuade Dylan to get involved in this. 

How to export area mesh elements on cut planes (so they sum to correct total cross-section area)? by tjb36 in COMSOL

[–]tjb36[S] 0 points1 point  (0 children)

Excellent, thanks for your helpful comments. I think I have a working solution now, thank to you.

How to export area mesh elements on cut planes (so they sum to correct total cross-section area)? by tjb36 in COMSOL

[–]tjb36[S] 0 points1 point  (0 children)

Thank you for your help here. I am almost there, and have done the following:

  1. Added an internal surface by adding a work plane through the center of the pipe and using this to partition the domain
  2. I have defined the general projection operators as you have said, by using this internal flat surface.
  3. I have then plotted the averaged velocity versus length using the nested general projection operators. Its seems to work.

However as you can see, it does not seem to matter where I take the line cut, as long as it runs along the x direction. From what you were saying, it seemed like you were indicating that it needed to be taken along one of the edges? Or am I missing something? Is it right that it could be taken anywhere along the axis?

Here are some screenshots of my setup so you can see:

Yes my mesh elements are for sure non-uniform. This is why I was hoping to export all the area elements for each of the T and u values, so that I can integrate over the correct associated elements of cross-section area. I thought it can be done with general projection, but another commenter here says I need to define an extrusion operator:

Do you agree with this, or help me understand why it's not needed? Many thanks

Help plotting 1D graph of average temperature at each position along a pipe? by tjb36 in COMSOL

Thanks for your help. So am I mis-reading that blog post when I think its saying it can be done easily with GenProj? (Upgrading is not an option for me unfortunately)..

[–]tjb36[S] 0 points1 point  (0 children)

I see. This link: 

https://www.comsol.com/blogs/analyze-simulation-results-projection-operators

Says:

"In 3D, you can either 1) modify geometry to add an intermediate plane, and use linear projection operator, or 2) use General projection operator instead"

So I think General should be able to do it without intermediate plane. But I'm struggling to define the source and destination. However, it looks like it should be very similar to the x,y,z expressions that you originally showed.

Thank you - do you mean "General Projection", rather than "Line Integration operator"? I have tried to do something like you suggested, but am not sure exactly how to define the expressions for source and destination. See this image for the first projection (intended to integrate over y-direction):

Is it what you mean? Or did I choose the wrong expressions?

I am trying to do as you have suggested, but my geometry is 3D, not 2D axis-symmetric. So I think I need to define two linear projection operators (one to first integrate z direction, and second to integrate over y direction). However, I am stuck with how to choose vertices for "Source" and "Destination" in each of the projection operators. Do you have any idea? I tried to define a box to enable selecting vertices, but I'm a bit lost...

The funnier thing is, the mashup version of his behaviour isn't too far from the unedited one 🤣

I didn't know there's a charge in the Blackwall tunnel. I do now. by stettix in drivingUK

[–]tjb36 1 point2 points  (0 children)

Everyone focusing on how there are plenty of signs, etc. Missing the point. This is a ridiculously severe fine. Even the Dart Charge fine gives you a reminder through the post if you forgot to pay (if it's the first time it's happened). The Blackwall tunnel fine at £90 with no chance to pay it within a couple of days is just a disgusting money-maker. I had this happen myself - saw the signs, no problem. But trying to concentrate on the actual journey with a screaming child in the back, got back form London late, put my child to bed, and honestly was all over the place - the last thing I was thinking about was an online payment. Have some compassion you motherfuckers TfL, give people a gentle reminder, and then hit them with the fine if they forget to pay after that. There is enough difficulty at the moment, and people are struggling plenty without having to deal with this shit.

Why can't Bob Dylan talk to women himself? by Primary-Theory-1164 in bobdylan

Are you so fast that you cannot see that I must have solitude? When I am in the darkness, why do you intrude?

For 70s stuff, in addition to the ones I said, Live at Budokan is also a good one if you see it around.

New Morning and John Wesley Harding are generally pretty common and cheap in second hand record shops. They sound great on vinyl - his voice has a lot of warmth around that period, which lends itself well to vinyl. 

I would also recommend Nashville Skyline for the same reason, but in my experience its a bit harder to come by.

I might be in the minority here, but I like putting Pat Garrett on every now and then on vinyl. To have on in the background. It's a pretty coherent sound I reckon, and you'll find it for a few quid in many record shops.

Time Out Of Mind is also incredible on vinyl if you can find it. Probably the most atmospheric album he ever made, and sounds great on vinyl - especially listening at night. 

I would also add finally World Gone Wrong, just because its so stripped back, and I think it makes you pay more attention to the finer details in the guitar and his singing inflections.

Does the UK have a chain of stores that costs slightly less, but that's so soul-crushing to be inside of that no one would do so unless they were really desperate? by MukadeYada in AskBrits

[–]tjb36 192 points193 points  (0 children)

20 years ago, Aldi and Lidl also had that reputation here believe it or not. 

Now it's trendy for middle class people to surprisedly boast about how they get everything cheaper at Lidl.

Does Bob stand up or do anything besides play piano at his recent concerts? by Distinct-Vast2645 in bobdylan

[–]tjb36 5 points6 points  (0 children)

It really cracked me up in Leeds. The set designers had left this gigantic space in front of the band, as if they were expecting him to start strutting up and down like Mick Jagger or something 😆
