pin - the problem with contacts
the problem with the model - contacts

<https://www.simscale.com/projects/gkondracki/bolt-test/>

this is such a simple model that count in various programs to check and learn contacts.

i have problems that i can not count - or the problem is in contact or boundary conditions.

hi greg ([@gkondracki](/forum/u/gkondracki)),

it is important that the fixation on the clevis does not include a constraint in the y-direction. this is because it shares an edge with the symmetry constraint (fix\_y) on the x-z plane. you can find a good explanation of why this is not allowed in the on-line help at the lin…

post code no i can’t, but you can look up the solution on the [hints page](http://forum.freecodecamp.org/t/freecodecamp-challenge-guide-profile-lookup/18259) if you’re ready to give up.

all you need to change is the placement of this line:

return "no such contact"

right now it’s inside the for loop (before the closing }), it needs to be outside the for loop (after the closing }) the block diagram in the [boron datasheets](https://docs.particle.io/datasheets/cellular/boron-datasheet/#block-diagram) shows this

and these are not the wire pins.

but you may want to try wire1 instead. hi [@banati.bodo](/u/banati.bodo)

the key here is to find which points are on the symmetry plane and keep them there with an onplane goal, then for the points ‘above’ the symmetry plane, use a transform goal to lock them to their mirror image below the symmetry plane.

[symmetry] Hello,  
  
Put in new batteries and try again.  
  
If new batteries did not solve the problem, the next thing to check would be the battery terminal.  
  
If
 the battery terminal is rusty, the battery power won't contact and the 
calculator won't turn on. So, use a flat small screw drive to scratch 
the battery terminal so that there would be contact.  
  
If the above
 is not the problem, the next to check would be the wire connecting the 
battery terminal to the the calculator's main board. There is a wire 
between the battery terminal and the calculator board. When the battery 
is inserted, the power from the battery goes from the terminal to the 
board through this wire. There is a possibility that this wire is cut 
in-between or is loosing contact. In this case, you need to get a small 
screw driver and carefully disassemble the calculator in order to check 
the wire.  
  
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.  
  
If non of the above helps, then it means the calculator is dead and needs a replacement.

"source… mapping is the 3rd rail of cad software. most pd's cannot maintain gis files, etc. the best solution i've seen is what we have now. our system uses google maps (browser based) with a system layer over it. so, either it geo codes the address after the call is saved or it uses the lat/long we enter on the geo file in our system. we can also geo code officer alerts to the map. so much easier. we also have browser based maps from our gis analyst that has more parcel info but only dispatchers reference it. best bet is to add a layer over the google map with your boundaries. i actually spoke to my vendor and they are going to add a boundary layer to our stuff as well. it's a good idea.

do you have any feedback on the difficulties i am having doing this and any suggestions as to how i should be approaching this problem?

perhaps there is something i’m clearly misunderstanding that can be addressed in a reference article or section of the documentat… This is indeed something of a problem. It is always difficult to jump into a new and large code-base. You should concentrate on any available overview documentation (e.g., explaining how it works or is structured), tutorials (e.g., showing how to make mods), and reference documentation (e.g., class references).


If you need to really dig into the source code of the library / application, then you need to find a relevant starting point. This could be something that is similar to what you want to do or modify. When you find a decent starting point, just look it up and try to understand what it does and how it works, and work your way out from there, by looking up related code (e.g., that is called within that code you are looking at, etc.). The "find in files" is definitely a central tool when exploring a code-base because it gives you an instant snapshot of where certain things are used and declared. For example, if you want to modify the behavior of class A, then there is a good chance that you will want to look at all the places where class A is used so that you can assess if your modified version will work or if you need to modify other things.


There is no doubt that doing this is hard and takes a lot of patience. I've done this several times with different code bases (some small ( < 50,000 LOCs ), some big ( > 1,000,000 LOCs )), and it's always a tedious process, especially if documentation is lacking (which it very often is). hi@thebatswhiskersjust checking in on your half hourly usage issue?i think you’re also effected by the situation outlined in this topic, where i confirm:please be advised that there is a known issue effecting some customers, where half hourly usage information is not populating ontoonline usage graphs, despite good smart meter comms, and a populated monthly chart.if you haven’t already, we’d appreciated it if you could make oursupport teamaware of this, so a ‘case’ can be raised, helping us to identify the volumes of those effected.
